Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a glue-wiping mechanism. Background Technology

[0002] Dispensing machines use dispensing heads to spray adhesive onto products. The most common type of dispensing head is the flat nozzle dispensing head. After the dispensing head has finished spraying the adhesive, some adhesive will remain on it. To ensure consistent adhesive application, the dispensing head usually needs to be wiped clean to prevent adhesive blockage and ensure dispensing quality.

[0003] The adhesive application mechanism is a common process module in dispensing machines. Conventional adhesive application mechanisms use a rolled-up cleanroom wipe to apply adhesive to the dispensing equipment. When the cleanroom wipe runs out, the unwinding and rewinding reels on the mechanism need to be removed and replaced with new cleanroom wipes before continuing operation. Replacing the cleanroom wipes in existing mechanisms requires setting up a workspace on the machine. Operators must reach into the machine to remove the unwinding and rewinding reels, replace the cleanroom wipes, and then reinstall the unwinding and rewinding reels. This method of replacement is time-consuming, inconvenient for operators, and impacts production efficiency. Utility Model Content

[0004] The technical problem solved by this utility model is that the existing adhesive application mechanism is slow in changing the lint-free cloth.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1As shown, an adhesive application mechanism includes a drive module 1 for providing power and an adhesive application module 2 detachably connected to the drive module 1. The adhesive application module 2 is pre-loaded with a roll of adhesive application material 3 and applies adhesive to the dispensing device. After the adhesive application material 3 is used up, the adhesive application module 2 can be directly removed from the drive module 1 and replaced with a new adhesive application module 2 (which also has a roll of adhesive application material 3 pre-loaded) to resume operation. This improves the replacement speed of the adhesive application material 3 (in this embodiment, a lint-free cloth is used as the adhesive application material) and increases overall work efficiency. The specific structure and assembly method of the adhesive application module 2 and the drive module 1 will be described in detail below.

[0031] like Figures 2 to 4 Specifically, the drive module 1 includes a fixed base 11 and an unwinding unit and a winding unit mounted on the fixed base 11. The winding unit includes a winding shaft 12, and the unwinding unit includes an unwinding shaft 13. The adhesive application module 2 includes a mounting base 21, on which a first bushing 22 and a second bushing 22A are rotatably connected. An unwinding tray 23 is connected to the first bushing 22, and a winding tray 24 is connected to the second bushing 22A. A magnetic damper 16 is connected to the unwinding shaft 13. The winding shaft 12 is power-transmittedly connected to the first bushing 22, and the unwinding shaft 13 is power-transmittedly connected to the second bushing 22A. The drive unit 15 is connected to the winding shaft 12. In this embodiment, the drive unit 15 is a stepper motor. The transmission shaft is a flexible transmission shaft.

[0032] The adhesive application module 2 is assembled onto the drive module 1, enabling power transmission between the take-up shaft 12 and the first bushing 22 of the take-up reel 24, and between the unwind shaft 13 and the second bushing 22A of the unwind reel 23. A roll of adhesive application material 3 is pre-installed on the unwind reel 23. The drive unit 15 drives the take-up shaft 12 to rotate, which in turn drives the take-up reel 24 to rotate synchronously. Simultaneously, the power is transmitted through the adhesive application material 3 to drive the unwind reel 23 to rotate synchronously, and the adhesive application material 3 is in the adhesive application working state. Tension control of the roll of adhesive application material 3 is achieved using a magnetic damper 16.

[0033] Specifically, the fixed base 11 is provided with a positioning post 18, and the mounting base 21 is provided with a positioning hole 29. When the mounting base 21 is assembled on the fixed base 11, the positioning post 18 and the positioning hole 29 form a back-locking structure. During assembly, it is only necessary to assemble the positioning post 18 and the positioning hole 29 accordingly. Since the positioning post 18 adopts a back-locking mechanism, the assembly structure of the positioning post 18 and the positioning hole 29 can be simplified, making it convenient for disassembly and assembly. At the same time, there are two positioning posts 18 and two positioning holes 29, which are arranged diagonally, simplifying the structure while ensuring a firm assembly.

[0034] Preferably, the fixing base 11 is also connected to a locking screw 19. After the positioning pin 18 is locked with the positioning hole 29, the locking screw 19 is screwed into the mounting base 21 to securely connect the fixing base 11 and the mounting base 21. After the positioning pin 18 and the positioning hole 29 are assembled, the locking screw 19 is inserted into the mounting base 21 to further improve the connection stability between the fixing base 11 and the mounting base 21.

[0035] Since it is impossible to guarantee that the angular phases of the first bushing 22 and the take-up shaft 12 and the second bushing 22A and the unwind shaft 13 on the new glue-applying module 2 are completely consistent when replacing the glue-applying module 2, corresponding assembly structures are set on the first bushing 22 and the take-up shaft 12 and the second bushing 22A and the unwind shaft 13 so that the two can be quickly assembled even when the angular phases are inconsistent.

[0036] like Figure 5 and Figure 6 As shown, preferably, the take-up shaft 12 and the unwind shaft 13 have elastic positioning elements 14. The first bushing 22 and the second bushing 22A have positioning grooves 221. The first bushing 22 is sleeved on the outside of the take-up shaft 12, so that the elastic positioning element 14 directly enters the positioning groove 221, or the elastic positioning element 14 enters the positioning groove 221 after rotating relative to the first bushing 22 with the take-up shaft 12, so that the take-up shaft 1 drives the first bushing 22 to drive the material tray to rotate. In other words, there are two situations when the take-up shaft 12 and the first bushing 22 are assembled. In the first situation, the elastic positioning element 14 is exactly aligned with the positioning groove 221. At this time, the take-up shaft 12 and the first bushing 22 are directly assembled in place, and the rotation of the take-up shaft 12 immediately drives the first bushing 22 to rotate. In the second scenario, the elastic positioning element 14 is misaligned with the positioning groove 221 in the circumferential direction. In this case, the take-up shaft 12 enters the first bushing 22, and the elastic positioning element 14 is compressed by the inner wall of the bushing 22, causing it to contract inward along the y-direction (since the circumferential position of the shaft and bushing is uncertain, the y-direction here should be understood as the circumferential direction perpendicular to the x-direction). At this time, power cannot be transmitted between the take-up shaft 12 and the first bushing 22, and the take-up shaft 12 rotates relative to the first bushing 22. After the take-up shaft 12 rotates a certain angle, the elastic positioning element 14 will align with the positioning groove 221 in the circumferential direction. At this point, the elastic positioning element 14 resets and enters the positioning groove 221, and power transmission is achieved between the take-up shaft 12 and the first bushing 22. The same principle applies between the unwind shaft 13 and the second bushing 22A. In this embodiment, the structure of the elastic positioning element 14 and the positioning groove 221 allows for easy replacement of the adhesive application module 2 without considering the assembly angle. The drive shaft and bushing 22 can be aligned directly to complete the assembly, thus improving the replacement efficiency of the adhesive application module 2.

[0037] Preferably, in this embodiment, the number of positioning slots 221 is 3.

[0038] Of course, the unwinding tray 23 and the take-up tray 24 have knobs that can be removed to replace the adhesive application part 3 in another process. This separates the process of replacing the adhesive application part 3, so as not to affect the efficiency of the adhesive application operation.

[0039] Specifically, the elastic positioning member 14 can extend and retract relative to the take-up shaft 12 and the unwind shaft 13 in the y-direction, and the positioning groove 221 is formed on the inner wall of the bushing 22 and arranged in the x-direction. The elastic positioning member 14 locks the bushing 22 in the y-direction, ensuring that the take-up shaft 12 and the unwind shaft 13 can transmit power to the bushing 22. Preferably, the front ends of the take-up shaft 12 and the unwind shaft 13 have a stepped structure, the elastic positioning member 14 is connected to the stepped structure, and the end of the elastic positioning member 14 protrudes from the outer circle of the drive shaft.

[0040] Preferably, the elastic positioning element 14 includes a housing 141 and a positioning pin 142. The housing 141 is mounted on the stepped structure along the y-direction. The positioning pin 142 is movably connected within the housing 141, and an elastic element 143 connects it to the housing 141. The positioning pin 142 can move along the y-direction within the housing 141. When the positioning pin 142 contacts the inner wall of the bushing 22, it is pressed down by the bushing 22 and enters the housing 141. The positioning pin 142 enters the positioning groove 221 area, and the elastic element 143 drives the positioning pin 142 to reset, and the positioning pin 142 enters the positioning groove 221, thereby realizing the power transmission connection between the drive shaft and the bushing 22. The stepped structure forms a machined surface, which facilitates the machining of mounting holes and the assembly of the elastic positioning element 14.

[0041] Preferably, the front ends of the take-up shaft 12 and the unwind shaft 13 are tapered head structures. The first bushing 22 and the second bushing 22A include guide openings with a reduced diameter along the x-direction and assembly holes. The take-up shaft 12 and the unwind shaft 13 enter the assembly holes along the guide openings. Under the action of the tapered heads, the take-up shaft 12 can be better inserted into the first bushing 22, and the unwind shaft 13 can be better inserted into the second bushing 22A.

[0042] Preferably, the take-up reel 24 and the unwind reel 23 are spaced apart along the z-direction, with the take-up reel 24 positioned above the unwind reel 23. Adjusting the take-up reel 24 and the unwind reel 23 to be positioned along the z-direction can reduce the space occupied in the y-direction, making it particularly suitable for dispensing machines with limited space in the y-direction.

[0043] Of course, the take-up tray 24 and the unwind tray 23 can also be set along the y-axis, or in other different positions, which can be adjusted according to actual needs.

[0044] Specifically, the mounting base 21 is equipped with a glue-applying seat 25 located above the take-up reel 24. The glue-applying seat 25 has glue-applying blocks 26. The glue-applying component 3, unwound from the unwinding reel 23, moves past the glue-applying blocks 26, applies glue to the dispensing head, and is then wound up by the take-up reel 24. Guide idler wheels 27, arranged along the y-direction, are rotatably connected to the glue-applying seat 25, symmetrically positioned on both sides of the glue-applying blocks 26. Multiple guide rollers 28 are arranged along the z-direction on the mounting base 21. The glue-applying component 3, unwound from the unwinding reel 23, passes sequentially through the guide rollers 28, guide idler wheels 27, glue-applying blocks 26, and guide idler wheels 27 before being wound up by the take-up reel 24. Figure 7 As shown, during operation, the adhesive application module 2 has the adhesive application component 3 unwound from the unwinding reel 23, moving upwards along the z-axis under the action of the guide roller 28, then passing along the y-axis through the adhesive application block 26 under the action of the guide idler wheel 27, and finally being wound up by the take-up reel 24 below. The adhesive application head moves above the adhesive application block 26 and then contacts the adhesive application component 3 to remove excess adhesive.

[0045] Since the operator needs to be reminded to replace the adhesive wiping module 2 before the adhesive wiping component 3 is used up, a detector 17 is required to monitor the usage status of the adhesive wiping component 3.

[0046] Preferably, the fixed base 11 is also equipped with a detector 17 located on the moving path of the adhesive wiping component 3. The detector 17 is located between the unwinding reel 23 and the adhesive wiping seat 25. The end of the adhesive wiping component 3 has a detection section of a certain length. The detector 17 detects the detection section and issues a material shortage alarm. In this embodiment, the detector 17 is a blue light diffuse reflection photodetector, and the detection section is made of transparent material. The detector 17 is set between the unwinding reel 23 and the adhesive wiping seat 25. When the last section of the adhesive wiping component 3 passes through the detector 17, and the unwinding reel 23 continues to unwind, the transparent detection section will pass through the detector 17. At this time, the detector 17 will issue an alarm, prompting the replacement of the adhesive wiping module 2. Even when the alarm is triggered, there are still adhesive wiping components 3 on the adhesive wiping seat 25, and adhesive wiping operations can still be performed. This can improve the detection accuracy of the adhesive wiping component 3 and avoid waste of adhesive wiping components.
