Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, and in particular to a dispensing head cleaning mechanism. Background Technology

[0002] Dispensing mechanisms are widely used in battery processing, semiconductor manufacturing, and other fields, and their dispensing accuracy directly affects the reliability and performance stability of products. After completing a dispensing cycle, the dispensing head usually leaves adhesive residue at its tip. This residue needs to be removed promptly; otherwise, it can easily lead to problems such as dispensing tailing, inaccurate dispensing volume, or dispensing position deviation. Currently, traditional cleaning methods often employ simple wiping, air blowing, or low-frequency solvent cleaning, which suffer from incomplete cleaning. Especially in high-speed dispensing applications, where cleaning time is significantly shortened, traditional cleaning methods are insufficient to meet the cleaning requirements of continuous production. Utility Model Content

[0003] Therefore, it is necessary to provide a dispensing head cleaning mechanism that can significantly improve the cleaning effect in response to the above problems.

[0004] A dispensing head cleaning mechanism includes a conveying component, a supporting component, and a clamping component. The conveying component can drive a wiping material belt to be conveyed along a conveying path. The supporting component is disposed on the conveying path of the wiping material belt. The clamping component has a wiping space that can be clamped or opened, and the wiping material belt can pass through the wiping space under the guidance of the supporting component.

[0005] In one embodiment, the conveying assembly includes an unwinding component and a winding component, and the support component is disposed between the unwinding component and the winding component, wherein the wiping material tape can be unwound by the unwinding component and wound up by the winding component.

[0006] In one embodiment, the conveying assembly further includes drive wheels, which are distributed between the unwinding member and the support assembly, and between the support assembly and the winding member.

[0007] In one embodiment, the support component can force the wiping strip to pass along a V-shaped path, and the V-shaped area formed by the wiping strip passing through the support component is located within the wiping space.

[0008] In one embodiment, the support assembly includes a first roller, a second roller, and a third roller, the center line connecting the first roller, the second roller, and the third roller forms a triangle, and the wiping material belt passing through the support assembly sequentially wraps around the first roller, the second roller, and the third roller.

[0009] In one embodiment, the inner wall of the wiping space is covered with a flexible padding layer.

[0010] In one embodiment, the flexible padding layer is configured as a sponge layer.

[0011] In one embodiment, the clamping assembly includes a gripper drive and at least two grippers, the at least two grippers surrounding the wiping space, and the at least two grippers being capable of clamping or opening under the drive of the gripper drive.

[0012] In one embodiment, the inner wall of each gripper is covered with a flexible pad.

[0013] In one embodiment, a mounting plate is also included, on which the conveying assembly, the support assembly, and the clamping assembly are all mounted.

[0014] The aforementioned dispensing head cleaning mechanism, when cleaning the dispensing head is required, first inserts the dispensing head into the wiping space, and then the clamping component squeezes the wiping tape inward to ensure the wiping tape effectively covers the dispensing head, thereby increasing the contact area between the wiping tape and the dispensing head. Furthermore, the squeezing action of the clamping component also increases the friction between the wiping tape and the dispensing head. As the conveying component drives the wiping tape forward, it cleans the dispensing head it contacts. Moreover, because both the contact area and the friction between the wiping tape and the dispensing head are increased, the aforementioned dispensing head cleaning mechanism significantly improves the cleaning effect on the dispensing head.

[0024] Please see Figure 1 and Figure 2 This utility model provides a dispensing head cleaning mechanism 600, which can clean the dispensing head (not shown) to remove residual adhesive, thereby ensuring the accuracy of subsequent dispensing. The dispensing head is generally elongated and hollow inside.

[0025] In one embodiment of the present invention, the dispensing head cleaning mechanism 600 includes a conveying component 610, a support component 620, and a clamping component 630. The conveying component 610 drives the wiping material belt 20 to be conveyed along the conveying path, and the support component 620 is disposed on the conveying path of the wiping material belt 20 and can force the wiping material belt 20 to pass through a V-shaped path.

[0026] The wiping material belt 20 is generally made of non-woven fabric. The conveying assembly 610 provides driving force to the wiping material belt 20 so that it can be conveyed. Specifically, in this embodiment, the conveying assembly 610 includes an unwinding component 611 and a winding component 612. The support assembly 620 is disposed between the unwinding component 611 and the winding component 612. The wiping material belt 20 can be unwound by the unwinding component 611 and wound up by the winding component 612.

[0027] Both the unwinding component 611 and the winding component 612 can adopt a spool structure. The unwinding component 611 is used to load clean wiping material tape 20, while the winding component 612 is used to wind up the used wiping material tape 20. The winding component 612 is generally connected to a winding motor (not shown in the figure) and can wind up the wiping material tape 20 under the drive of the winding motor. The unwinding component 611 can be passively unwound under the traction of the winding component 612, or it can be connected to the unwinding motor (not shown in the figure) to achieve active unwinding.

[0028] Furthermore, in this embodiment, the conveying assembly 610 also includes drive wheels 613, with drive wheels 613 distributed between the unwinding member 611 and the support assembly 620, and between the support assembly 620 and the winding member 612. The wiping material belt 20 is wound around the drive wheels 613, which are generally connected to a drive motor (not shown) and can provide driving force for the wiping material belt 20. In this way, the force on the wiping material belt 20 is more uniform in its extension direction, thereby preventing the wiping material belt 20 from breaking or wrinkling.

[0029] The support component 620 guides and redirects the wiping tape 20, and the clamping component 630 has a wiping space (not shown), which can clamp or open. Guided by the support component 620, the wiping tape passes through the wiping space. Furthermore, during the clamping process, the clamping component 630 can compress the area of ​​the wiping tape 20 passing through the wiping space from the outside in.

[0030] When cleaning the dispensing head, the dispensing head is first inserted into the wiping space, and then the clamping component 630 clamps the wiping space, thereby squeezing the wiping tape 20 inward so that the wiping tape 20 can better cover the dispensing head, thus increasing the contact area between the wiping tape 20 and the dispensing head. Moreover, under the squeezing action of the clamping component 630, the friction between the wiping tape 20 and the dispensing head is also increased. As the conveying component 610 drives the wiping tape 20 to be conveyed, the wiping tape 20 can wipe and clean the dispensing head in contact with it. Moreover, since the contact area between the wiping tape 20 and the dispensing head and the friction between them are increased, the cleaning effect on the dispensing head is significantly improved compared to traditional wiping, blowing, or low-frequency solvent cleaning methods.

[0031] Specifically, in this embodiment, the support component 620 forces the wiping material belt 20 to pass along a V-shaped path, and the V-shaped area formed by the wiping material belt 20 passing through the support component 620 is located within the wiping space. The support component 620 causes the wiping material belt 20 to turn, thereby bending the wiping material belt 20 into a V-shape.

[0032] Further, in this embodiment, the support assembly 620 includes a first guide roller 621, a second guide roller 622, and a third guide roller 623. The center line connecting the first guide roller 621, the second guide roller 622, and the third guide roller 623 forms a triangle. The wiping material belt 20 passing through the support assembly 620 sequentially wraps around the first guide roller 621, the second guide roller 622, and the third guide roller 623. The wiping material belt 20 changes direction when wrapping around the first guide roller 621, the second guide roller 622, and the third guide roller 623, thereby bending into a V-shape. That is, the portion of the wiping material belt 20 that wraps around the first guide roller 621, the second guide roller 622, and the third guide roller 623 is V-shaped.

[0033] When the dispensing head is inserted into the wiping space, it is inserted into the V-shaped area of ​​the wiping tape 20. The V-shaped wiping tape 20 has a larger contact area with the dispensing head, which can better cover the dispensing head, thereby further improving the cleaning effect on the dispensing head.

[0034] Specifically, in this embodiment, the inner wall of the wiping space is covered with a flexible padding layer 631. The flexible padding layer 631 can be a sponge layer or a foam layer, capable of elastic deformation. When the wiping space of the clamping assembly 630 presses the V-shaped area of ​​the wiping material strip 20 inward, the flexible padding layer 631 can deform according to the outer wall contour of the dispensing head, thereby better covering the dispensing head.

[0035] Specifically, in this embodiment, the clamping assembly 630 includes a gripper drive (not shown) and at least two grippers 632, which enclose a wiping space. The gripper drive can be a gripper cylinder, and the grippers 632 can open or close under the drive of the gripper cylinder. Utilizing the grippers 632 in conjunction with the gripper cylinder allows the clamping assembly 630 to have a simple structure and fast response. Furthermore, the inner wall of each gripper 632 is generally provided with a flexible padding layer 631.

[0036] More specifically, in this embodiment, the dispensing head cleaning mechanism 600 also includes a mounting plate 640, on which the conveying assembly 610, the support assembly 620, and the clamping assembly 630 are all mounted. This allows the dispensing head cleaning mechanism 600 to be moved as a whole, facilitating the switching of its position according to working conditions.

[0037] The aforementioned dispensing head cleaning mechanism 600, when cleaning the dispensing head is required, first inserts the dispensing head into the V-shaped area formed by the wiping tape 20 and the support component 620. Then, the clamping component 630 presses the V-shaped area of ​​the wiping tape 20 inward, so that the wiping tape 20 can better cover the dispensing head, thereby increasing the contact area between the wiping tape 20 and the dispensing head. Moreover, under the squeezing action of the clamping component 630, the friction between the wiping tape 20 and the dispensing head is also increased. As the conveying component 610 drives the wiping tape 20 to be conveyed, the wiping tape 20 can wipe and clean the dispensing head it contacts. Furthermore, since both the contact area between the wiping tape 20 and the dispensing head and the friction between the wiping tape 20 and the dispensing head are increased, the aforementioned dispensing head cleaning mechanism 600 can significantly improve the cleaning effect on the dispensing head.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
