Description

Technical Field

[0001] The present application relates to the technical field of dispensing needles, and in particular to a dispensing needle cleaning device. Background Art

[0002] During the precision dispensing process, glue drips, strings, and residues inevitably form on the outside of the dispensing needle. If these waste glue residues are not removed promptly and effectively, they can lead to a series of serious problems. For example, dripping waste glue can contaminate products in non-target areas; solidified residual glue can directly clog the dispensing needle, resulting in inaccurate dispensing amounts and seriously affecting dispensing accuracy, continuity, and product yield.

[0003] Traditional dispensing needle cleaning devices are commonly used, but they generally suffer from complex structures and low automation levels. In particular, they require frequent downtime to replace cleaning consumables.

[0012] One or more technical solutions provided in this application have at least the following technical effects:

[0013] The present embodiment of the utility model adopts a dispensing needle cleaning device. The cleaning component includes two rotating wheels, one of which is a driving wheel and the other is a driven wheel. The driving wheel is connected to the output end of the driving member. One end of the cleaning cloth is wrapped around the driving wheel, and the other end of the cleaning cloth is wrapped around the driven wheel after passing through the sponge installation box. The driving member drives the driving wheel to rotate; the driving member drives the driving wheel to rotate, so that the driving wheel can automatically reel in the used dirty cleaning cloth segment and simultaneously pull the unused cleaning cloth segment to the working position of the sponge installation box. The cleaning device also includes a spare roll, a connecting shaft and a telescopic assembly. The spare roll is mounted on the connecting shaft. One end of the connecting shaft is connected to the output end of the driving member, and the other end can be slidably connected to the telescopic assembly. The connecting shaft has a mounting hole radially extending into it, housing a telescopic baffle. A push rod can move within the operating hole. When the cleaning device is operating, the push rod is pushed toward the drive element, causing the rod's tapered surface to contact the telescopic baffle, causing it to extend outward and separate the spare roll. When a new cleaning cloth needs to be loaded, the push rod is manually pulled in the opposite direction, eliminating its force on the telescopic baffle. The elastic element causes the baffle to move inward, releasing the obstruction on the spare roll and facilitating the removal of discarded cleaning cloth rolls or the installation of spare rolls. This mechanism avoids frequent manual replacement operations and extends the life of a single load of cleaning cloths, significantly reducing the number and time of downtime required to replace consumables, lowering labor costs and improving the efficiency of continuous operation of the equipment. This application solves the technical problems of complex structure, low degree of automation and frequent replacement of cleaning consumables in traditional dispensing needle cleaning devices, which reduces production efficiency; the spare roll can be quickly locked and released through simple axial push-pull operations, which simplifies the operating steps. When the currently used cleaning cloth roll is exhausted, it can be quickly switched to the spare roll, thereby minimizing the downtime required for cloth roll replacement and further improving production efficiency.

DETAILED DESCRIPTION

[0023] 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 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.

[0024] In the description of the embodiments of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present invention. The terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0025] The present invention provides a dispensing needle cleaning device. Figure 1-6 As shown, it includes a cleaning component 1 and a cleaning cloth 2; the cleaning component 1 includes a sponge mounting box 11, a driving component, a motor box 12, a support frame 13 and two rotating wheels 14; one end of the support frame 13 is connected to the workbench, and the other end of the support frame 13 is connected to the sponge mounting box 11; the motor box 12 is connected to the sponge mounting box 11, the driving component is arranged in the motor box 12, the output end of the driving component is connected to one of the rotating wheels 14, and the other rotating wheel 14 is rotatably connected to the motor box 12, and the two rotating wheels 14 are arranged on both sides of the sponge mounting box 11; one end of the cleaning cloth 2 is wrapped around one of the rotating wheels 14, and the other end of the cleaning cloth 2 bypasses the sponge mounting box 11 and is wrapped around the other rotating wheel 14.

[0026] For example, the cleaning cloth 2 is a non-woven fabric. The sponge mounting box 11 provides rigid support for the non-woven fabric. Due to its elasticity, the non-woven fabric maintains close contact with the dispensing needle surface during wiping, effectively removing drips, stringiness, and residue. Furthermore, the material of the sponge mounting box 11 helps absorb some of the glue solution, significantly improving the cleaning effect of the dispensing needle.

[0027] Exemplarily, the dispensing needle moves to the cleaning station according to the procedure, and the dispensing needle contacts the cleaning cloth 2. The driving part is started according to the instruction, and the driving part can drive the active wheel to rotate and roll up the used non-woven fabric segment, and at the same time pull out a new non-woven fabric segment from the driven wheel to cover the working surface of the sponge installation box 11, thereby preparing for the next cleaning. This process is carried out automatically and no manual intervention is required to change the cloth. It should be noted that the dispensing needle is moved to the cleaning station by the moving component. The cleaning station refers to the position of the non-woven fabric on the sponge installation box 11. During cleaning, the dispensing needle abuts against the non-woven fabric on the sponge installation box 11, and the active wheel drives the non-woven fabric to move on the sponge installation box 11. During the movement, the non-woven fabric can wipe the residual glue on the dispensing needle, thereby ensuring the cleanliness of the dispensing needle.

[0028] Exemplarily, the moving component is configured as a three-axis moving mechanism, which includes a supporting foot, a transverse mounting backplate, a first moving member, a second moving member and a third moving member; one end of the supporting foot is connected to the workbench, the other end of the supporting foot is connected to the fixed end of the first moving member, and the movable end of the first moving member is connected to the transverse mounting backplate; the fixed end of the second moving member is connected to the transverse mounting backplate, the movable end of the second moving member is connected to the fixed end of the third moving member, and the movable end of the third moving member is connected to the dispensing needle. The three-axis moving mechanism can drive the dispensing needle to scrape and wipe the glue after gluing.

[0029] In the embodiment of this application, Figure 1-6As shown, the dispensing needle cleaning device also includes a spare roll 3, a telescopic component 4 and a connecting shaft 5; one end of the connecting shaft 5 is connected to the output end of the driving member, and the other end of the connecting shaft 5 is slidably connected to one end of the telescopic component 4; the spare roll 3 is sleeved on the connecting shaft 5; the other end of the telescopic component 4 is slidably connected in the radial direction of the connecting shaft 5, and the other end of the telescopic component 4 is configured to abut against the end face of the spare roll 3.

[0030] In the embodiment of this application, Figure 1-6 As shown, the telescopic assembly 4 includes a push rod 41 and a telescopic baffle 42; an operating hole is opened in the axial direction of the connecting shaft 5, and a mounting hole is opened in the radial direction of the connecting shaft 5; one end of the push rod 41 extends into the operating hole, and the other end of the push rod 41 is slidably connected to the end of the connecting shaft 5 away from the driving member; the telescopic baffle 42 is arranged in the mounting hole, and the telescopic baffle 42 is slidably connected to the connecting shaft 5; when the push rod 41 moves toward the direction close to the driving member, the telescopic baffle 42 moves in the direction away from the axis of the connecting shaft 5 under the action of the push rod 41, at this time, the telescopic baffle 42 abuts against the end face of the spare roll 3; when the push rod 41 moves in the direction away from the driving member, the telescopic baffle 42 moves in the direction close to the axis of the connecting shaft 5, at this time, the telescopic baffle 42 releases the restriction on the movement of the spare roll 3.

[0031] In the embodiment of this application, Figure 1-6 As shown, the telescopic assembly 4 also includes an elastic member; a plurality of telescopic blocking pieces 42 are provided, and the plurality of telescopic blocking pieces 42 are symmetrically arranged; one end of the elastic member is connected to one of the telescopic blocking pieces 42, and the other end of the elastic member is connected to the oppositely arranged telescopic blocking piece 42, and the elastic member is configured to move the telescopic blocking piece 42 toward the direction close to the axis center of the connecting shaft 5.

[0032] For example, when the cleaning device is working, the push rod 41 is pushed toward the driving member, and the conical surface of the push rod 41 can abut against the telescopic baffle 42, thereby extending the telescopic baffle 42 outward and separating the spare roll 3. At this time, the push rod 41 is connected to the connecting shaft 5 through a thread; when the cleaning device needs to load a new cleaning cloth 2, the push rod 41 is manually pulled in the opposite direction, and the force of the push rod 41 on the telescopic baffle 42 disappears. The elastic member can move the telescopic baffle 42 inward, thereby releasing the obstruction to the spare roll 3, making it easier to remove the discarded cleaning cloth 2 or install the spare roll 3. This mechanism avoids frequent manual replacement operations and extends the use time of a single load of cleaning cloth 2, thereby significantly reducing the number and time of downtime to replace consumables, reducing labor costs, and improving the efficiency of continuous operation of the equipment.

[0033] In the embodiment of this application, Figure 1-6As shown, the cleaning assembly 1 also includes a first fixed pulley 16 and a second fixed pulley 17; the first fixed pulley 16 and the second fixed pulley 17 are arranged at intervals, and the first fixed pulley 16 and the second fixed pulley 17 are both rotatably connected to the motor box 12; one end of the cleaning cloth 2 is wrapped around one of the rotating pulleys 14, and the other end of the cleaning cloth 2 is sequentially passed around the first fixed pulley 16, the second fixed pulley 17 and the sponge mounting box 11 and wrapped around the other rotating pulley 14.

[0034] In the embodiment of this application, Figure 1-6 As shown, the end of the push rod 41 close to the driving member is configured to be tapered.

[0035] In the embodiment of this application, Figure 1-6 As shown, the cleaning assembly 1 further includes a collecting barrel 15 ; the collecting barrel 15 is disposed on a side of the motor box 12 close to the glue dispensing needle, and the collecting barrel 15 can collect glue dripping from the glue dispensing needle.

[0036] Exemplarily, the collection bucket 15 is located below the wiping area and can directly collect the waste glue liquid dripping from the dispensing needle during the cleaning process, thereby effectively avoiding the problem of waste glue dripping into non-target areas and causing contamination, improving the cleanliness of the working area, and reducing subsequent cleaning work.

[0037] Exemplarily, it also includes a scraper barrel assembly 6, one end of which is connected to the workbench, and the other end of which can abut against the glue dispensing needle. The scraper barrel assembly 6 is configured to scrape off the glue hanging on the glue dispensing needle.

[0038] For example, the glue scraping barrel assembly 6 and the cleaning assembly 1 are both located below the dispensing needle. The dispensing needle is automatically programmed to move the dispensing needle to the glue scraping barrel assembly 6 after each dispensing, thereby preventing glue from sticking to the dispensing needle and affecting the next dispensing effect. When the equipment is suspended or restored due to special circumstances, the dispensing needle is moved to the glue wiping position of the cleaning assembly 1 by the moving assembly for wiping, thereby keeping the dispensing needle clean. Glue sticking refers to residual glue at the output end of the dispensing needle.

[0039] Exemplarily, the dispensing needle is moved to the target position by a moving component. The present application is provided with a cleaning component 1 and a scraper barrel component 6, wherein the scraper barrel component 6 and the cleaning component 1 are arranged at intervals on the workstation table. The moving component can drive the dispensing needle to move to the cleaning station of the cleaning component 1 or the glue removal barrel 61. The present application chooses to use the scraper barrel component 6 or the cleaning component 1 in different situations. After the dispensing needle finishes gluing a workpiece each time, the dispensing needle is moved to the scraper barrel component 6 for scraping glue through the moving component. Specifically, a steel wire 62 with a diameter of 0.2 mm is provided on the glue removal barrel 61. When scraping glue is required, the moving component drives the dispensing needle to scrape on the steel wire 62, thereby avoiding glue hanging on the dispensing needle and affecting the effect of the next gluing; after scraping the glue, the moving component drives the dispensing needle to move to the cleaning station of the cleaning component 1, and wipes the residual glue on the dispensing needle, thereby further ensuring the cleaning effect. When the device is suspended or abnormally restored due to special circumstances, the dispensing needle is moved to the cleaning station of the cleaning component 1 by the moving component for wiping, so that the dispensing needle is kept clean.

[0040] like Figure 7 As shown, it also includes a glue scraping barrel assembly 6, which includes a glue removal barrel 61 and a steel wire 62; the glue removal barrel 61 is connected to the workbench, and a steel wire 62 is provided at the entrance of the glue removal barrel 61, which can scrape off the glue hanging on the dispensing needle.

[0041] Exemplarily, the glue removal barrel 61 is connected to the workbench, and a steel wire 62 is provided on the glue removal barrel 61. The moving component drives the glue dispensing needle to move, so that the steel wire 62 scrapes off the glue on the glue dispensing needle and collects the excess glue into the glue removal barrel 61 for reuse.

[0042] Exemplarily, the glue scraping barrel assembly 6 further includes a glue scraping blade 63 , which is disposed at the entrance of the glue dispensing barrel 61 . The glue scraping blade 63 can scrape the glue hanging on the glue dispensing needle.

[0043] Exemplarily, the scraper blade 63 of the glue scraper barrel assembly 6 is arranged at the entrance of the glue discharge barrel 61 to assist in scraping away the residual glue on the glue dispensing needle.

[0044] Exemplarily, the automatic program runs the dispensing needle, and after each glue application, the dispensing needle is moved to the steel wire 62 of the glue scraper barrel for scraping glue, thereby avoiding glue hanging on the dispensing needle and affecting the accuracy of the next glue application; when the equipment is suspended or abnormally restored due to special circumstances, the dispensing needle is moved to the glue wiping position of the cleaning component 1 for wiping, and the glue on the dispensing needle can be wiped by the cleaning cloth 2, so that the dispensing needle is kept clean.

[0045] Exemplarily, the glue scraping barrel assembly 6 further comprises two steel wire pressing blocks 64, which are respectively connected to the entrance of the glue discharging barrel 61 and oppositely arranged.

[0046] Exemplarily, the two steel wire pressing blocks 64 are arranged in parallel at two sides of the entrance of the glue discharging barrel 61, and the two ends of the steel wire 62 are connected to the two steel wire pressing blocks 64 by bolts.

[0047] Exemplarily, the glue scraping barrel assembly 6 further comprises a heightening block 65 and a positioning seat 66, one end of the heightening block 65 is connected to the workbench, the other end of the heightening block 65 is connected to one end of the positioning seat 66, and the other end of the positioning seat 66 is connected to the glue discharging barrel 61.

[0048] The various embodiments in the specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0049] The above examples are only used to illustrate the technical solutions of the present application, and are not limited to the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
