Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dispensing technology, and in particular to a needle degreasing mechanism and a dispensing device. BACKGROUND

[0002] Dispensing is a production process that applies glue, oil or other liquids to products for the purpose of sticking, sealing, insulating, fixing, smoothing, etc. Whether it is an automatic dispensing machine or manual dispensing, the glue needs to be pushed out of the needle. Since the glue has a certain viscosity, it will adhere to the outer periphery of the needle and form an expansion part, so that the subsequent glue will be affected by the expansion part during the flow-out process, resulting in reduced dispensing accuracy.

[0003] Therefore, it is urgent to research a needle degreasing mechanism and a dispensing device to solve the above problems. SUMMARY

For example, the lower side can include the positive lower side, the left lower side, the right lower side, the front lower side, and the rear lower side, etc.

[0054] As Figures 1 to 9As shown, the embodiment provides a needle degumming mechanism, which comprises a base 100, a cleaning table 200, a cleaning driving assembly 300, two clamping assemblies 400 and a cleaning assembly 500. Wherein the cleaning table 200 is rotatably arranged on the base 100; the cleaning driving assembly 300 is arranged on the base 100, and the output end is in transmission connection with the cleaning table 200 to drive the cleaning table 200 to rotate; the two clamping assemblies 400 are both slidingly arranged on the cleaning table 200, and can approach or move away from each other; the cleaning assembly 500 comprises a bearing piece 510 and a collecting piece 520, the bearing piece 510 is used for placing unused cleaning tape 1000, and the collecting piece 520 is used for collecting used cleaning tape 1000, the collecting piece 520 and the bearing piece 510 form two layers of cleaning tape 1000, and the two layers of cleaning tape 1000 can be clamped between the two clamping assemblies 400, and under the clamping of the two clamping assemblies 400, the needle can be clamped between the two layers of cleaning tape 1000.

[0055] With the above structure, when the needle is clamped, the cleaning table 200 rotates, so that the cleaning tape 1000 can rotate around the needle to scrape the adhesive liquid attached to the needle onto the cleaning tape 1000, so as to restore the clean state of the needle, thereby ensuring the precision of subsequent dispensing. The arrangement of the two layers of cleaning tape 1000 ensures that the needle is uniformly stressed and does not bend, and also avoids the clamping assembly 400 from sticking to the adhesive; finally, the double-layer cleaning tape 1000 can clean the needle twice, greatly improving the cleaning efficiency and cleaning effect.

[0056] In order to improve the automation degree of cleaning, in some embodiments, the cleaning assembly 500 further comprises a collecting driving piece 530, the collecting piece 520 is rotatably arranged on the cleaning table 200, the collecting driving piece 530 is arranged on the cleaning table 200 and can rotate synchronously with the cleaning table 200, the output end of the collecting driving piece 530 is in transmission connection with the collecting piece 520 to drive the collecting piece 520 to rotate relative to the cleaning table 200, and the collecting piece 520 is used for winding and collecting the used cleaning tape 1000. The rotating arrangement of the collecting piece 520 can wind the used cleaning tape 1000, which is convenient for subsequent unified processing. Further, the wound cleaning tape 1000 is in the form of a roll, and the side with adhesive faces inwards and the smooth side faces outwards, so that the roll-shaped cleaning tape 1000 will not be loose, which is convenient for subsequent transfer.

[0057] Since the collecting piece 520 can rotate relative to the cleaning table 200, during use, the collecting piece 520 can rotate while the cleaning table 200 rotates, so that the cleaning belt 1000 can be quickly replaced, the cleaning efficiency is improved, and during the replacement process, the cleaning belt 1000 moves relative to the needle, so that the needle can also be cleaned, and the cleaning efficiency of the needle is further improved. Of course, when the viscosity of the glue is large, the clamping assembly 400 can be separated first, and then the collecting driving piece 530 is actuated to replace the clean cleaning belt 1000.

[0058] Regarding the specific structure of the collecting piece 520, in some embodiments, the collecting piece 520 includes a connecting mounting portion 521 and a collecting portion 522, the mounting portion 521 is connected with the output end of the collecting driving piece 530, and the collecting portion 522 is a cylindrical structure; the collecting portion 522 is provided with at least one clamping groove 523 penetrating through the side wall of the collecting portion 522 vertically, and the clamping groove 523 is used for clamping the end of the cleaning belt 1000. The clamping groove 523 is provided to facilitate the fixation of the cleaning belt 1000, so that the subsequent cleaning belt 1000 is wound on the collecting portion 522; the cylindrical structure helps to reduce the material consumption, reduce the weight, reduce the power demand of the collecting driving piece 530, and reduce the use cost; finally, the cylindrical structure also helps to improve the bending resistance and ensure the tension of the cleaning belt 1000, so as to ensure the cleaning effect of the needle, and the cylindrical structure is convenient for opening the clamping groove 523.

[0059] Exemplarily, the clamping groove 523 is provided with two clamping grooves 523, and the two clamping grooves 523 are provided to improve the convenience of clamping the cleaning belt 1000. When the cleaning belt 1000 is installed, the clamping groove 523 with a suitable angle can be selected to improve the efficiency of the cleaning belt 1000 into the clamping groove 523. Optionally, the collecting piece 520 is made of metal materials such as stainless steel, and the two clamping grooves 523 are symmetrically arranged about the axis of the collecting portion 522, so that the collecting portion 522 is divided into two collecting blocks by the clamping groove 523; the collecting block can be plastically deformed, so that the distance between the two collecting blocks can be adjusted, so as to adjust the width of the clamping groove 523, and then the cleaning belt 1000 with different thicknesses can be adapted.

[0060] In order to facilitate processing, in other embodiments, the collecting piece 520 is a columnar structure, and the collecting piece 520 is provided with a collecting groove for clamping the end of the cleaning belt 1000.

[0061] As to the specific structure of the carrier 510, in some embodiments, the carrier 510 is rotatably arranged on the cleaning table 200 and can be penetrated into and fixed in the fixed ring of the roll-shaped cleaning tape 1000, so that the roll-shaped cleaning tape 1000 rotates synchronously with the carrier 510. The cleaning assembly 500 further comprises a damping member 540 arranged between the cleaning table 200 and the carrier 510, so that the carrier 510 and the cleaning table 200 remain stationary when the drag force generated by the rotation of the collection member 520 is less than a preset value. This arrangement enables the placement and tensioning of the cleaning tape 1000 to be completed by only the collection member 520 and the carrier 510, which is a clever structure; wherein the tensioning force is controlled by the damping force generated by the damping member 540. Specifically, the damping member 540 is a damping pad and has a damping hole, the lower end of the carrier 510 is connected with a carrier shaft 541 and rotates synchronously with the carrier shaft 541, the carrier shaft 541 is rotatably arranged on the cleaning table 200, the lower bottom surface of the cleaning table 200 is provided with a bottom flange 542, the carrier shaft 541 penetrates through the bottom flange 542 and penetrates through the damping hole and rotates synchronously with the damping pad, a carrier nut 543 is screwed on the carrier shaft 541, and the damping pad is clamped between the end surface of the carrier nut 543 and the bottom flange 542. The circumference of the carrier shaft 541 has a tangent plane, and the profile of the damping hole is the same as the cross-sectional profile of the tangent plane of the carrier shaft 541. The bearing is arranged between the bottom flange 542 and the carrier shaft 541. Optionally, the upper top of the cleaning table 200 is provided with a top flange 544, and the carrier shaft 541 penetrates through the top flange 544. The bearing is arranged between the top flange 544 and the carrier shaft 541.

[0062] The carrier 510 comprises a carrier table 511 and two carrier rods 512, the carrier table 511 is connected with the carrier shaft 541 and rotates synchronously with the carrier shaft 541, the carrier rod 512 is slidingly arranged between the two carrier tables 511, the fixed ring is sleeved on the outside of the two carrier rods 512, and a spring is arranged between the two carrier rods 512 to push the two carrier rods 512 away from each other.

[0063] The carrier 510 and the collection member 520 are each provided with two and correspond to each other, one carrier 510 and the corresponding collection member 520 are located on one side of the needle, and the other carrier 510 and the corresponding collection member 520 are located on the other side of the needle, and each carrier 510 and the corresponding collection member 520 form a layer of cleaning tape 1000. The arrangement of the two carriers 510 and the two collection members 520 enables the cleaning tape 1000 to be replaced only by moving a distance slightly greater than one half of the circumference of the needle after cleaning the needle.

[0064] In other embodiments, the carrier 510 and the collection member 520 are each provided with one, and the cleaning table 200 is provided with a transfer member, the cleaning tape 1000 is folded back after being unwound from the carrier 510 and is collected by the collection member 520.

[0065] In some embodiments, the needle degumming mechanism further comprises a bottom support 550 provided on the cleaning table 200 and comprising a first channel and a second channel; wherein the two bearing rods 512 are arranged in the first channel, and the collection member 520 is arranged in the second channel. The clean cleaning tape 1000 in a roll is supported by the bottom support 550, and the used cleaning tape 1000 in a roll is also supported by the bottom support 550, which improves the neatness of the used cleaning tape 1000 in a roll. In addition, when cleaning is needed, the bottom support 550 can be removed and cleaned, which is convenient for cleaning and avoids the adhesive liquid from occupying other complex rotating mechanisms.

[0066] The needle degumming mechanism further comprises a clamping driving member 600 provided on the cleaning table 200 and having two output ends, which are respectively connected to the two clamping assemblies 400 to drive the two clamping assemblies 400 to move closer to or away from each other. The above arrangement realizes the automatic action of the clamping assembly 400 and improves the degumming efficiency.

[0067] When a new roll of cleaning tape 1000 is used, the radius of the roll-shaped cleaning tape 1000 on the bearing member 510 is large, and the radius of the roll-shaped cleaning tape 1000 on the collection member 520 is small. As the cleaning work proceeds, the radius of the roll-shaped cleaning tape 1000 on the bearing member 510 gradually decreases, and the radius of the roll-shaped cleaning tape 1000 on the collection member 520 gradually increases. However, during use, the collection driving member 530 needs to be stopped from rotating, and then the clamping driving member 600 acts to clamp the two layers of cleaning tape 1000. The different radii of the cleaning tape 1000 on the bearing member 510 and the collection member 520 result in different tension forces of the clamped cleaning tape 1000. Too large or too small tension force will affect the cleaning effect, and too small tension force will also cause winding, affecting the normal progress of the cleaning work.

[0068] Therefore, the needle degumming mechanism further comprises four guide shafts 560 rotatably provided on the cleaning table 200. Each two guide shafts 560 form a group, and the two groups of guide shafts 560 are arranged corresponding to the two clamping assemblies 400. The two guide shafts 560 in the same group are arranged at intervals and have parallel arrangement directions parallel to the direction of the clamping gap of the two clamping assemblies 400 and are arranged on the two sides of the corresponding clamping assembly 400. This arrangement ensures that the angle of the cleaning tape 1000 clamped by the clamping assembly 400 remains unchanged when it enters the clamping assembly 400, ensures that the tension force of the cleaning tape 1000 is the same, and thus ensures the cleaning effect.

[0069] In some embodiments, the clamping assembly 400 comprises a clamping block 410, a buffer 420 and a fixing member 430, the clamping block 410 is in transmission connection with the output end of the clamping driving member 600, the fixing member 430 is detachably connected to the clamping block 410, and the buffer 420 is clamped between the clamping block 410 and the fixing member 430, and part of the buffer 420 is located outside the clamping block 410 and the fixing member 430 along the side of the two clamping assemblies 400 that are close to each other.

[0070] The cleaning driving assembly 300 comprises a driving wheel 310, a driven wheel 320, a cleaning driving member 330 and a rotating shaft 340, wherein the cleaning driving member 330 is arranged on the base 100, the driving wheel 310 is arranged on the output end of the cleaning driving member 330, the rotating shaft 340 is rotatably arranged on the base 100 and connected with the cleaning platform 200 at one end and connected with the driven wheel 320 at the other end, and the driven wheel 320 and the driving wheel 310 are in transmission connection. Among them, the driving wheel 310 and the transmission wheel are synchronous wheels, and the two are in transmission connection through a synchronous belt. Further, the rotating cylinder 110 is arranged on the base 100, and the rotating shaft 340 penetrates through the rotating cylinder 110, so as to ensure the stability of the rotation of the cleaning platform 200.

[0071] In order to avoid too much glue liquid on the needle during cleaning, the needle needs to be preliminarily cleaned, and in combination with the Figure 6 and Figure 7 In some embodiments, the needle degumming mechanism further comprises a blowing assembly 700, and the blowing assembly 700 comprises a blowing member 710 and a collection barrel 720. Among them, the blowing member 710 is provided with a plurality of cleaning channels 711 arranged at intervals for accommodating the needle, the blowing member 710 further has a gas inlet 712 and a plurality of blowing channels in communication with the gas inlet 712 and the cleaning channels 711, the diameters of the gas outlets 713 of the plurality of blowing channels in communication with the corresponding cleaning channels 711 decrease, so that the flow rate of the blown gas increases; the collection barrel 720 is arranged below the blowing member 710 for collecting glue liquid. The blowing channel is inclined downward along the radial direction of the cleaning channel 711.

[0072] The above arrangement allows the glue liquid outside the needle to be partially blown off, thereby facilitating subsequent cleaning. In addition, the arrangement of a plurality of cleaning channels 711 and the increasing flow rate of the gas in each cleaning channel 711 allows the needle to be first placed in a cleaning channel 711 with a smaller gas flow, and then placed in a cleaning channel 711 with a larger gas flow after the large glue liquid drops, thereby further removing the glue liquid; finally, since each blowing channel shares one gas inlet 712, the connection of the gas source and the subsequent operation are more simple.

[0073] Need to be explained, when the needle is placed in the cleaning channel 711, the part with glue is located below the cleaning channel 711, that is, outside the cleaning channel 711, to avoid the glue sticking to the side wall of the cleaning channel 711 during the blowing process.

[0074] To improve the cleaning effect, further, one cleaning channel 711 corresponds to several blowing channels, and the gas outlets 713 of each blowing channel are arranged around the axis of the cleaning channel 711, wherein each blowing channel shares one gas inlet 712, and the lengths of each blowing channel are different, so that the time nodes of the airflow from the gas inlet 712 into the blowing member 710, flowing through each blowing channel and reaching each corresponding gas outlet 713 are different. This kind of setting makes the airflow from the gas outlets 713 in different directions blow out at different times after the needle passes through the cleaning channel 711, so that the glue liquid swings back and forth to facilitate separation from the needle, and finally all the gas outlets 713 have airflow to facilitate the glue liquid to be blown down into the collection barrel 720.

[0075] The embodiment also provides a dispensing equipment, which comprises a rack, a scanning mechanism 800, a dispensing mechanism 900 and the needle degumming mechanism in any of the above embodiments arranged on the rack, the scanning mechanism 800 is used for scanning a dispensing piece located at a scanning station of the rack, and the dispensing mechanism 900 is used for dispensing glue for the dispensing piece at a dispensing station.
