Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing, and in particular to a needle glue removal mechanism and glue dispensing equipment. Background Art

[0002] Glue dispensing is a production process that involves applying, filling, or dripping glue, oil, or other liquids onto products to make them stick, fill, insulate, fix, or smooth their surfaces. Whether it is an automatic glue dispensing machine or manual glue dispensing, the glue needs to be pushed out of the needle. Since the glue has a certain viscosity, it will adhere to the periphery of the needle and form an expansion part, which will affect the subsequent glue flow during the expansion process, resulting in reduced glue dispensing accuracy.

[0003] Therefore, it is urgent to study a needle degumming mechanism and a glue dispensing device to solve the above problems. Summary of the invention

In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0051] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints.

[0054] like Figures 1 to 9As shown, this embodiment provides a needle degumming mechanism, which includes a base 100, a cleaning table 200, a cleaning drive assembly 300, two clamping assemblies 400 and a cleaning assembly 500. Among them, the cleaning table 200 is rotatably arranged on the base 100; the cleaning drive assembly 300 is arranged on the base 100, and the output end is transmission-connected with the cleaning table 200 to drive the cleaning table 200 to rotate; the two clamping assemblies 400 are both slidably arranged on the cleaning table 200, and can approach or move away from each other; the cleaning assembly 500 includes a carrier 510 and a collecting member 520, the carrier 510 is used to place unused cleaning tapes 1000, and the collecting member 520 is used to collect used cleaning tapes 1000, two layers of cleaning tapes 1000 are formed between the collecting member 520 and the carrier 510, and the two layers of cleaning tapes 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 tapes 1000.

[0055] With the above-mentioned structure, when the needle is clamped, the cleaning table 200 rotates, so that the cleaning belt 1000 can rotate around the needle to scrape the glue attached to the needle onto the cleaning belt 1000, so that the needle is restored to a clean state, thereby ensuring the accuracy of subsequent glue dispensing. Among them, the setting of the two-layer cleaning belt 1000 ensures that the needle is evenly stressed and will not bend, and can also prevent the clamping component 400 from sticking glue; finally, the double-layer cleaning belt 1000 can double clean the needle, greatly improving the cleaning efficiency and cleaning effect.

[0056] To improve the automation of cleaning, in some embodiments, the cleaning assembly 500 also includes a collecting drive 530, a collecting member 520 is rotatably arranged on the cleaning table 200, and the collecting drive 530 is arranged on the cleaning table 200, and can rotate synchronously with the cleaning table 200, and the output end of the collecting drive 530 is connected to the collecting member 520 in a transmission manner to drive the collecting member 520 to rotate relative to the cleaning table 200, and the collecting member 520 is used to wind and collect the used cleaning tape 1000. The way in which the collecting member 520 is rotatably arranged can wind up the used cleaning tape 1000, which is convenient for subsequent unified processing. Further, the cleaning tape 1000 after winding is in a roll shape, and the side with glue faces inward, and the smooth side faces outward, so that the rolled cleaning tape 1000 will not be loose, which is convenient for subsequent transfer.

[0057] Since the collecting member 520 can rotate relative to the cleaning table 200, when in use, the collecting member 520 can rotate while the cleaning table 200 rotates, thereby realizing the rapid replacement of the cleaning belt 1000 and improving the cleaning efficiency. In addition, during the replacement process, the cleaning belt 1000 moves relative to the needle head, which can also realize the cleaning of the needle head and further improve the cleaning efficiency of the needle head. Of course, when the viscosity of the glue is relatively large, the clamping assembly 400 can be separated first, and then the collecting driving member 530 can be operated to replace the clean cleaning belt 1000.

[0058] Regarding the specific structure of the collecting member 520, in some embodiments, the collecting member 520 includes a mounting portion 521 and a collecting portion 522 connected to each other, the mounting portion 521 is connected to the output end of the collecting drive 530, and the collecting portion 522 is a cylindrical structure; the collecting portion 522 is provided with at least one clamping groove 523 along the side wall vertically penetrating the collecting portion 522, and the clamping groove 523 is used to clamp the end of the cleaning belt 1000. The setting of the clamping groove 523 facilitates the fixing of the cleaning belt 1000, so that the subsequent cleaning belt 1000 is wound around the collecting portion 522; the cylindrical structure helps to reduce the material consumption, reduce the weight, reduce the power demand of the collecting drive 530, and reduce the use cost; finally, the cylindrical structure also helps to improve the bending resistance, ensure the tension of the cleaning belt 1000, thereby ensuring the cleaning effect on the needle, and the cylindrical structure facilitates the opening of the clamping groove 523.

[0059] Exemplarily, two clamping grooves 523 are provided, and the provision of two clamping grooves 523 helps to improve the convenience of clamping the cleaning tape 1000. When installing the cleaning tape 1000, a clamping groove 523 with a suitable angle can be selected to improve the efficiency of placing the cleaning tape 1000 into the clamping groove 523. Optionally, the collecting member 520 is made of metal 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 grooves 523; the collecting blocks can produce plastic deformation, so that the distance between the two collecting blocks can be relatively adjusted, thereby adjusting the width of the clamping groove 523, and then can adapt to cleaning tapes 1000 of different thicknesses.

[0060] To facilitate processing, in other embodiments, the collecting member 520 is a columnar structure, and the collecting member 520 is provided with a collecting groove, which is used to clamp the end of the cleaning belt 1000 .

[0061] Regarding the specific structure of the carrier 510, in some embodiments, the carrier 510 is rotatably disposed on the cleaning table 200, and can be passed through and fixed in the fixed ring of the rolled cleaning tape 1000, so that the rolled cleaning tape 1000 and the carrier 510 rotate synchronously, and the cleaning assembly 500 also includes a damping member 540, which is disposed between the cleaning table 200 and the carrier 510, so that when the drag force generated by the collection member 520 during the rotation process is less than a preset value, the carrier 510 and the cleaning table 200 remain stationary. This arrangement allows the placement and tensioning of the cleaning tape 1000 to be completed only by the collection member 520 and the carrier 510, and the structure is ingenious; wherein the tensioning force is controlled by the damping force generated by the damping member 540. Specifically, the damping member 540 is a damping gasket and has a damping hole. The lower end of the bearing member 510 is connected to a bearing shaft 541 and rotates synchronously with the bearing shaft 541. The bearing shaft 541 is rotatably arranged on the cleaning table 200. The lower bottom surface of the cleaning table 200 is installed with a bottom flange 542. The bearing shaft 541 is penetrated in the bottom flange 542 and penetrated in the damping hole and rotates synchronously with the damping gasket. The bearing nut 543 is screwed on the bearing shaft 541, and the damping gasket is clamped between the bearing nut 543 and the end face of the bottom flange 542. The circumference of the bearing shaft 541 has a section, and the profile of the damping hole is the same as the cross-sectional profile of the bearing shaft 541 at the section. Among them, a bearing is arranged between the bottom flange 542 and the bearing shaft 541. Optionally, a top flange 544 is installed on the top of the cleaning table 200, and the bearing shaft 541 is penetrated in the top flange 544. A bearing is arranged between the top flange 544 and the bearing shaft 541.

[0062] The supporting member 510 includes a supporting platform 511 and two supporting rods 512. The supporting platform 511 is connected to the supporting shaft 541 and rotates synchronously therewith. The supporting rod 512 is slidably arranged between the two supporting platforms 511. The fixed ring is arranged outside the two supporting rods 512, and a spring is arranged between the two supporting rods 512 to push the two supporting rods 512 away from each other.

[0063] Two carriers 510 and two collecting members 520 are provided, and they correspond one to one. One carrier 510 and the corresponding collecting member 520 are located on one side of the needle, and the other carrier 510 and the corresponding collecting member 520 are located on the other side of the needle. A layer of cleaning tape 1000 is formed between each carrier 510 and the corresponding collecting member 520. The arrangement of two carriers 510 and two collecting members 520 allows the cleaning tape 1000 to be replaced after cleaning the needle by only moving a distance slightly greater than half of the circumference of the needle.

[0064] In other embodiments, there is one carrier 510 and one collector 520 , and a transfer member is disposed on the cleaning table 200 . After the cleaning tape 1000 is rolled out from the carrier 510 , it is folded back through the transfer member and collected by the collector 520 .

[0065] In some embodiments, the needle glue removal mechanism further includes a bottom support 550, which is disposed on the cleaning table 200 and includes a first channel and a second channel; wherein two bearing rods 512 are disposed through the first channel, and a collecting member 520 is disposed through 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 winding of the used cleaning tape 1000; in addition, when cleaning is required, the bottom support 550 can be disassembled for cleaning, which is convenient for cleaning and prevents glue from occupying other complex rotating mechanisms.

[0066] The needle degumming mechanism further includes a clamping drive member 600, which is disposed on the cleaning table 200 and has two output ends, and the two output ends of the clamping drive member 600 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 of cleaning tape 1000 on the carrier 510 is large, and the radius of the roll of cleaning tape 1000 on the collecting member 520 is small. As the cleaning work proceeds, the radius of the roll of cleaning tape 1000 on the carrier 510 gradually decreases, and the radius of the cleaning tape 1000 on the collecting member 520 gradually increases. However, during use, it is necessary to stop the collection drive member 530 from rotating before the clamping drive member 600 operates again to clamp the two layers of cleaning tape 1000. The different radii of the cleaning tape 1000 on the carrier 510 and the collecting member 520 result in different tensioning forces of the clamped cleaning tape 1000. Too much or too little tensioning force will affect the cleaning effect. Too little tensioning force will cause entanglement, affecting the normal progress of the cleaning work.

[0068] To this end, the needle degumming mechanism also includes four guide shafts 560 rotatably arranged on the cleaning table 200, wherein every two guide shafts 560 form a group, and the two groups of guide shafts 560 are respectively arranged corresponding to the two clamping assemblies 400, and the two guide shafts 560 in the same group are arranged at intervals, and the arrangement direction of the two is parallel to the direction of the gap between the two clamping assemblies 400, and are respectively arranged on both sides of the corresponding clamping assemblies 400 to ensure that the cleaning belt 1000 clamped by the clamping assembly 400 maintains an unchanged angle when entering the clamping assembly 400, thereby ensuring that the tension of the cleaning belt 1000 is the same, thereby ensuring the cleaning effect.

[0069] In some embodiments, the clamping assembly 400 includes a clamping block 410, a buffer 420 and a fixing member 430. The clamping block 410 is transmission-connected to the output end of the clamping drive 600. The fixing member 430 is detachably connected to the clamping block 410. The buffer 420 is clamped between the clamping block 410 and the fixing member 430. Along the side of the two clamping assemblies 400 that are close to each other, a portion of the buffer 420 is located outside the clamping block 410 and the fixing member 430.

[0070] The cleaning drive assembly 300 includes a driving wheel 310, a driven wheel 320, a cleaning drive member 330 and a rotating shaft 340, wherein the cleaning drive member 330 is arranged on the base 100, the driving wheel 310 is arranged at the output end of the cleaning drive member 330, the rotating shaft 340 is rotatably arranged on the base 100, and one end is connected to the cleaning table 200, and the other end is connected to the driven wheel 320, and the driven wheel 320 and the driving wheel 310 are connected by transmission. Among them, the driving wheel 310 and the transmission wheel are both synchronous wheels, and the two are connected by a synchronous belt transmission. Further, the rotating cylinder 110 is arranged on the base 100, and the rotating shaft 340 is penetrated in the rotating cylinder 110 to ensure the stability of the rotation of the cleaning table 200.

[0071] To avoid excessive glue on the needle during cleaning, the needle needs to be cleaned initially. Figure 6 and Figure 7 As shown, in some embodiments, the needle glue removal mechanism further includes a blowing assembly 700, and the blowing assembly 700 includes a blowing member 710 and a blowing member 710. Among them, the blowing member 710 is provided with a plurality of cleaning channels 711 arranged at intervals for accommodating the needle, and the blowing member 710 also has an air inlet 712 and a plurality of blowing channels connected to the air inlet 712 and connected to the cleaning channel 711, and the diameters of the air outlets 713 of the plurality of blowing channels connected to the corresponding cleaning channels 711 are gradually reduced so that the flow rate of the blown gas is gradually increased; the collecting barrel 720 is arranged below the blowing member 710 for collecting the glue liquid. The blowing channel is inclined inward and downward along the radial direction of the cleaning channel 711.

[0072] The above arrangement enables the glue 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 airflow speed in each cleaning channel 711 allow the needle to be placed in the cleaning channel 711 with a smaller airflow first, and when a large piece of glue drops, the needle is placed in the cleaning channel 711 with a larger airflow, thereby further removing the glue; finally, since each blowing channel shares a common air inlet 712, the connection of the air source and subsequent operations are simpler.

[0073] It should be noted that 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 prevent the glue from sticking to the side wall of the cleaning channel 711 during the purging process.

[0074] In order to improve the cleaning effect, further, a cleaning channel 711 corresponds to several blowing channels, and the air outlets 713 of each blowing channel are arranged around the axis of the cleaning channel 711, wherein each blowing channel shares an air inlet 712, and the lengths of each blowing channel are different, so that after the airflow enters the blowing member 710 from the air inlet 712, it flows through each blowing channel and reaches each corresponding air outlet 713 at different time nodes. This arrangement makes it possible for the airflow to be blown out from the air outlets 713 in each direction 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 air outlets 713 have airflow to facilitate blowing the glue liquid downward into the collection bucket 720.

[0075] This embodiment also provides a dispensing device, including a frame and a scanning mechanism 800, a dispensing mechanism 900 and a needle degumming mechanism in any of the above embodiments arranged on the frame, the scanning mechanism 800 is used to scan the parts to be dispensed located at the scanning station of the frame, and the dispensing mechanism 900 is used to dispense glue for the parts to be dispensed at the dispensing station.

[0076] Combination Figure 1 , Figure 8 and Fig. 9 As shown, the dispensing mechanism 900 includes a dispensing robot 910 and a dispensing fixing component, which is arranged at the end of the dispensing robot 910 and is used to fix the dispensing head 950.
