[0058] Please see Figure 1 The diagram shows a structural schematic of a wiping platform, including a support platform 101, a support column 102, a feeding roller 103, a receiving roller 104, and a wiping tape 105. The wiping tape 105 is released from the feeding roller 103, passes through the support column 102 and the support platform 101, and is wound up by the receiving roller 104. The wiping tape 105 is positioned above the side of the support platform 101 facing away from the feeding roller 103. A dispensing needle applies adhesive to the wiping tape 105 on the support platform 101. After the dispensing needle completes wiping, the wiping tape 105 with wiping marks on the support platform 101 is retrieved by the receiving roller 104, making it difficult to check the previous wiping process. Furthermore, during operator inspections, abnormal wiping marks may move below the support platform 101, making it impossible for operators to visually observe the wiping marks from the dispensing needle, thus hindering timely detection of any abnormalities in the dispensing needle.

[0059] This application provides a glue-wiping device for a dispensing machine nozzle and a dispensing machine, which can fully display the glue-wiping traces so that operators can promptly detect abnormalities in the dispensing needle.

[0067] Example 1

[0068] This embodiment provides a glue-wiping device for a dispensing machine nozzle. Please refer to [link to relevant documentation]. Figure 2 The image shows a schematic diagram of the adhesive wiping device for a dispensing machine nozzle according to one embodiment of the present invention. The adhesive wiping device for a dispensing machine nozzle includes a drive motor 201, a rotating rod 207, a turntable 202, an adhesive wiping cloth 203, and an adhesive valve lens 206. The rotating rod 207 is located above the drive motor 201 and connected to the output end of the drive motor 201 to rotate under the drive of the drive motor 201. The central axis of the rotating rod 207 is arranged in a vertical direction. The turntable 202 is located above the rotating rod 207 and connected to the rotating rod 207. The adhesive wiping cloth 203 covers the upper surface of the turntable 202. The adhesive valve lens 206 is located above the adhesive wiping cloth 203.

[0069] Specifically, when the adhesive wiping device for the dispensing machine nozzle is in operation, the adhesive wiping device for the dispensing machine nozzle is installed on the dispensing machine. Please refer to [link to relevant documentation]. Figure 3 The diagram shows a schematic of the dispensing machine of this utility model in one embodiment. The glue valve 205 and the dispensing needle 204 are located above the wiping cloth 203. The glue valve lens 206 is fixed to the side wall of the glue valve 205. The wiping device for the dispensing machine nozzle works in coordination with the glue valve 205 so that the wiping cloth 203 can fully display the wiping marks of the dispensing needle 204.

[0070] To better illustrate the cooperation between the glue-wiping device for the dispensing machine nozzle and the glue valve 205, please refer to [link / reference needed]. Figure 4 and Figure 5 , Figure 4 This is a top view showing the adhesive application device for a dispensing machine nozzle in one working state according to the present invention. Figure 5 This is a top view showing another working state of the adhesive wiping device for a dispensing machine nozzle according to this utility model. When the dispensing needle 204 needs to wipe adhesive, the adhesive valve 205 first moves the dispensing needle 204 downward, causing the needle tip of the dispensing needle 204 to slightly press down on the adhesive wiping cloth 203. The adhesive wiping cloth 203 absorbs the residual adhesive on the dispensing needle 204. Subsequently, the adhesive valve 205 moves the dispensing needle 204 upward, causing the dispensing needle 204 to detach from the residual adhesive and the adhesive wiping cloth 203. The residual adhesive absorbed by the adhesive wiping cloth 203 forms an adhesive wiping mark 213. At this time, the drive motor 201 drives the turntable 202 to rotate clockwise via the rotating rod 207 (e.g., Figure 3The dispensing needle 204 moves to a preset angle θ (as indicated by arrow A) to complete one application of adhesive. If the dispensing needle 204 needs to apply adhesive again, the above operation is repeated until the turntable 202 rotates to the starting position. At this time, multiple adhesive marks 213 will be formed on the adhesive cloth 203, and the multiple adhesive marks 213 are evenly distributed along a circular trajectory. Subsequently, the adhesive valve 205 moves the dispensing needle 204 along the radial direction of the turntable 202 (e.g., as indicated by arrow A) to complete one application of adhesive. Figure 3 Moving the dispensing needle 204 a preset distance L (in the direction indicated by arrow B) and repeating the above operation, multiple adhesive marks 213 evenly distributed along another circular trajectory are obtained until the dispensing needle 204 moves to the edge of the turntable 202 along direction B in the figure, at which point the operation stops. Finally, the glue valve lens 206 takes a picture of the adhesive marks 213 on the adhesive cloth 203 for record-keeping, and the operator then replaces the adhesive cloth 203. Thus, the operator can observe all the adhesive marks 213 on the same adhesive cloth 203 and view all the adhesive marks 213 on different adhesive cloths 203 at any time, thereby promptly detecting any abnormalities in the dispensing needle 204. The preset angle θ can be freely adjusted according to the radius of the circular trajectory and the number of adhesive marks 213 on the circular trajectory, and the preset distance L can also be freely adjusted according to the density of the adhesive marks 213 on the adhesive cloth 203. In this embodiment, the preset angle θ decreases as the radius of the circular trajectory increases. It should be noted that the preset angle θ and the preset distance L should be such that there is a gap between the adhesive marks 213 (i.e., different adhesive marks 213 will not overlap each other) so that the operator can observe all the adhesive marks 213 of the dispensing needle 204.

[0071] As an example, a coupling 208 is provided between the drive motor 201 and the rotating rod 207.

[0072] As an example, the adhesive wiping cloth 203 includes an adhesive wiping portion 2031 covering the turntable 202 and a fixing portion 2032 hanging around the turntable 202. The adhesive wiping device also includes a fixing strap 209 sleeved around the fixing portion 2032 to fix the fixing portion 2032 around the turntable 202, preventing relative movement between the adhesive wiping cloth 203 and the turntable 202, thereby avoiding affecting the adhesive wiping marks 213 of the dispensing needle 204. It should be noted that... Figure 2 To facilitate the demonstration of the structure of the fixing part 2032, the fixing part 2032 is not completely hanging down to the side of the turntable 202.

[0073] As an example, the wiping cloth 203 may be square, circular, or hexagonal in shape.

[0074] As an example, the dispensing machine also includes a control switch 210, which is connected to the drive motor 201 via a signal line 211. The control switch 210 is used to control the on / off state of the drive motor 201, thereby adjusting the preset angle θ of the rotation of the turntable 202.

[0075] For example, please refer to Figure 6 The image shows a top view of the turntable 202 of the adhesive wiping device for a dispensing machine nozzle according to one embodiment of the present invention. The upper surface of the turntable 202 is provided with a circular recess 216. The center normal of the circular recess 216 is on the same straight line as the central axis of the turntable 202. The circular recess 216 causes the adhesive wiping part 2031 of the adhesive wiping cloth 203 to be suspended above the upper surface of the turntable 202. When the dispensing needle 204 presses down on the adhesive wiping cloth 203, the adhesive wiping cloth 203 can better absorb the residual adhesive on the dispensing needle 204.

[0076] The adhesive wiping device for the nozzle of the dispensing machine in this embodiment includes a drive motor, a rotating rod, a turntable, an adhesive wiping cloth, and an adhesive valve lens. When the adhesive wiping device for the nozzle of the dispensing machine is working, it is installed on the dispensing machine. By coordinating with the valve of the dispensing machine, the adhesive wiping cloth can fully display the adhesive wiping marks of the dispensing needle, making it easy for the operator to detect abnormalities of the dispensing needle in a timely manner.

[0080] As an example, the glue valve 205 is electrically connected to a computer, which contains glue application software and movement software. When the glue application software issues a glue application command, the glue valve 205 drives the glue dispensing needle 204 to complete one glue application operation. When the movement software issues a movement command, the glue valve 205 drives the glue dispensing needle 204 to move a preset distance L along the radius of the turntable 202.

[0081] As an example, the bottom of the glue valve 205 is provided with a flow guide seat 214, and the bottom of the flow guide seat 214 is detachably provided with a fixing sleeve 215, which is fixedly connected to the glue dispensing needle 204.

[0082] As an example, the dispensing nozzle of the dispensing needle 204 is connected to a ball bearing (not shown).

[0083] The dispensing machine in this embodiment uses the aforementioned glue-wiping device for the dispensing machine nozzle, which can completely display the glue-wiping traces, making it easier for operators to detect abnormalities in the dispensing needle in a timely manner, thereby improving the production efficiency and yield of the dispensing machine.

[0084] In summary, the adhesive wiping device for a dispensing machine nozzle of this invention includes a drive motor, a rotating rod, a turntable, an adhesive wiping cloth, and an adhesive valve lens.
