Abstract
Description
Technical Field
[0001] This utility model relates to the field of dispensing machine needle cleaning technology, specifically an organic solvent wiping component suitable for cleaning dispensing machine needles. Background Technology
[0002] After the dispensing operation is completed, whether it is pneumatic or static dispensing, glue will always remain at the tip of the needle. If these residues are not removed in time, they will cause serious problems. For example, the residual glue may drip, evaporate or solidify in subsequent production, contaminating the product surface, equipment table or even other work stations, resulting in product scrap or poor appearance. Moreover, glue residue (especially wet glue before curing) will gradually solidify and dry at the tip of the needle, or react with substances in the air, eventually clogging the needle orifice, seriously affecting dispensing accuracy, flow stability and repeatability, and even causing the needle to be scrapped.
[0003] Currently, the most frequently used needle wiping components are dry wipes with lint-free cloths, which are driven by a geared motor to rotate the lint-free cloth and wipe the needle tip. However, this method is essentially a dry wipe, relying on the physical cleaning ability of the lint-free cloth to wipe the tip of the needle. This method has limited effectiveness in removing residue and is difficult to achieve thorough cleaning. In addition, the existing wiping method also has the pain point of replacing the lint-free cloth. Each time the lint-free cloth is replaced, it is cumbersome, slow, and inefficient. Utility Model Content
[0004] The purpose of this invention is to provide an organic solvent wiping assembly suitable for cleaning dispensing machine needles, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an organic solvent wiping assembly suitable for cleaning dispensing machine needles, comprising a mounting plate, a rotatable damping shaft mounted on the mounting plate, a geared motor mounted on the mounting plate, a limit mechanism mounted on both the output shaft of the geared motor and the damping shaft, an unwinding roller mounted on the upper limit mechanism of the damping shaft, and a take-up roller mounted on the limit mechanism on the output shaft of the geared motor, wherein the take-up roller and the unwinding roller are connected by a lint-free cloth;
[0006] A spraying mechanism is used to spray alcohol onto a cleanroom cloth, and the spraying mechanism is mounted on a mounting plate.
[0007] Preferably, the mounting plate is also fixed with a support plate, which is located directly above the spraying mechanism. The support plate and the lint-free cloth are slidably connected. The support plate has a round hole for alcohol to pass through. The support plate can support the lint-free cloth, which facilitates the subsequent contact between the lint-free cloth and the dispensing head to clean the adhesive.
[0008] Preferably, the mounting plate is also connected to a guide roller by a bearing, and the guide roller is connected to the cleanroom cloth. Through the action of the guide roller, the cleanroom cloth can be guided and limited, ensuring the stability of the cleanroom cloth's movement.
[0009] Preferably, the limiting mechanism includes an installation sleeve that is fixed to the damping shaft and the output shaft of the reduction motor, and a fixing seat is fixed inside the installation sleeve by bolts. The installation sleeve is connected to the unwinding roller and the winding roller by sleeve connection. With the above structure, the unwinding roller and the winding roller can be easily disassembled and assembled.
[0010] Preferably, the mounting sleeve and the limiting plate are connected by a sleeve, and the limiting plate contacts the unwinding roller and the winding roller to achieve positioning. Furthermore, the limiting plate and the pressure ring are connected by a nested connection. Through the above structure, the stability of the installation of the unwinding roller and the winding roller can be guaranteed.
[0011] Preferably, the pressure ring is penetrated by a locking rotating rod, and two limiting shafts are fixed on the locking rotating rod. The limiting shafts engage with the fixed seat to achieve a locking effect. Through the locking effect between the limiting shafts and the fixed seat, the positioning function of the unwinding roller and the winding roller can be achieved.
[0012] Preferably, the spraying mechanism includes a liquid storage box fixed to a mounting plate, and a fixing plate is fixed inside the liquid storage box. A liquid level sensor for detecting the liquid level in the liquid storage box is installed on the fixing plate. The liquid storage box is used to store alcohol. Through the above structure, the liquid level of alcohol in the liquid storage box can be detected so that staff can replenish it in a timely manner.
[0013] Preferably, a miniature water pump is installed on the lower end face of the liquid storage box, and the inlet of the miniature water pump is connected to the liquid storage box through a conduit, and the outlet of the miniature water pump is connected to a nozzle through a conduit. At the same time, the nozzle is fixed inside the liquid storage box. With the above structure, alcohol can be sprayed onto the lint-free cloth, thereby keeping the lint-free cloth in a wet state and ensuring the lint-free cloth's wiping effect on the adhesive material of the dispensing needle.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This organic solvent wiping component for cleaning dispensing machine needles uses a spray mechanism to spray alcohol onto the lint-free cloth, thus keeping the cloth moist. Alcohol has excellent dissolving and peeling properties for adhesives, and its high volatility significantly enhances the lint-free cloth's ability to clean needles, effectively ensuring the cleaning effect of the needles.
[0016] 2. This organic solvent wiping assembly for cleaning dispensing machine needles adopts a quick-release limiting mechanism. The locking and unlocking of the unwinding or rewinding roller can be achieved simply by rotating the locking lever by 90°, thereby effectively improving the convenience of disassembling and assembling the unwinding or rewinding roller, and thus effectively improving the disassembly and assembly efficiency of the unwinding or rewinding roller.

[0024] 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.
[0025] Please see Figures 1-6This utility model provides a technical solution: an organic solvent wiping assembly suitable for cleaning dispensing machine needles, including a mounting plate 1, a rotatable damping shaft 4 mounted on the mounting plate 1, a geared motor 5 mounted on the mounting plate 1, a limit mechanism 6 mounted on the output shaft of the geared motor 5 and the damping shaft 4, and an unwinding roller 7 mounted on the upper limit mechanism 6 of the damping shaft 4, and a take-up roller 8 mounted on the limit mechanism 6 on the output shaft of the geared motor 5, and the take-up roller 8 and the unwinding roller 7 are connected by a lint-free cloth 9;
[0026] The spraying mechanism 10 is used to spray alcohol onto the cleanroom cloth 9. The spraying mechanism 10 is mounted on the mounting plate 1.
[0027] The mounting plate 1 is also connected to a guide roller 3 by a bearing, and the guide roller 3 is connected to the cleanroom cloth 9. The limiting mechanism 6 includes a mounting sleeve 601 that is fixed to the output shaft of the damping shaft 4 and the geared motor 5. A fixing seat 602 is fixed inside the mounting sleeve 601 by bolts. The mounting sleeve 601 is sleeved to the unwinding roller 7 and the winding roller 8. The mounting sleeve 601 is sleeved to the limiting plate 603. The limiting plate 603 contacts the unwinding roller 7 and the winding roller 8 to achieve positioning. The limiting plate 603 is nested to the pressure ring 604. The pressure ring 604 is penetrated by a locking rod 605. Two limiting shafts 606 are fixed on the locking rod 605. The limiting shafts 606 engage with the fixing seat 602 to achieve locking.
[0028] When using an organic solvent suitable for cleaning dispensing machine needles to wipe the components, such as Figures 1-6 As shown, first, the unwinding roller 7 and the take-up roller 8 are installed. During installation, the unwinding roller 7 is fitted with the mounting sleeve 601 on the damping shaft 4, and the take-up roller 8 is fitted with the mounting sleeve 601 on the output shaft of the reduction motor 5. The limiting plate 603 is then fitted with the mounting sleeve 601 to achieve front and rear limiting of the unwinding roller 7 and the take-up roller 8. Next, the pressure ring 604 is nested with the limiting plate 603, and the locking rod 605 passes through the limiting plate 603, the pressure ring 604, and the fixed base 602. When engaged, the upper limit shaft 606 of the locking lever 605 is inserted into the vertical slot on the fixed seat 602. By rotating the locking lever 605 by 90°, the limit shaft 606 is engaged with the fixed seat 602, thereby achieving a locking effect and realizing the installation and fixation of the unwinding roller 7 and the winding roller 8. According to the above principle, by rotating the locking lever 605 in the opposite direction, the limit shaft 606 and the fixed seat 602 can be unlocked, so as to realize the disassembly and replacement of the unwinding roller 7 and the winding roller 8, effectively improving the convenience of operation.
[0029] Mounting plate 1 is also fixed with a support plate 2, which is located directly above the spraying mechanism 10. The support plate 2 is slidably connected to the lint-free cloth 9. The support plate 2 has a round hole for alcohol to pass through. The spraying mechanism 10 includes a storage box 1001 fixed on mounting plate 1. A fixing plate 1002 is fixed inside the storage box 1001. A liquid level sensor 1003 for detecting the liquid level in the storage box 1001 is installed on the fixing plate 1002. The storage box 1001 is used to store alcohol. A miniature water pump 1004 is installed on the lower end face of the storage box 1001. The inlet of the miniature water pump 1004 is connected to the storage box 1001 through a conduit. The outlet of the miniature water pump 1004 is connected to the nozzle 1005 through a conduit. The nozzle 1005 is fixed inside the storage box 1001.
[0030] During the use of the device, such as Figures 1-6 As shown, the geared motor 5 drives the take-up roller 8 to take up the cleanroom cloth 9. At this time, the unwind roller 7 automatically releases the cleanroom cloth 9, thereby achieving the replacement of the cleanroom cloth 9 on the upper part of the tray 2. When the needle is wiped with adhesive, the alcohol in the liquid storage box 1001 is sprayed onto the cleanroom cloth 9 on the upper part of the tray 2 through the nozzle 1005 and the round hole on the tray 2 by the action of the micro water pump 1004 and the conduit, so that the cleanroom cloth 9 on the upper part of the tray 2 is in a wet state. When the dispensing needle moves to contact and rub against the cleanroom cloth 9 on the upper part of the tray 2, the alcohol on the cleanroom cloth 9 can effectively dissolve the adhesive at the end of the dispensing needle and glass, thereby effectively removing the adhesive at the end of the dispensing needle.
