[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-6 As shown, this utility model discloses a glue-applying needle mechanism for a dispensing machine, comprising: Support frame 1; The adhesive application assembly 2 includes a mounting plate 21, a clamping cylinder 22, a strip 23, and multiple support rollers 24. The mounting plate 21 has a feeding shaft 25 and a receiving shaft 26 on its surface. The clamping cylinder 22 is positioned between the feeding shaft 25 and the receiving shaft 26. Multiple support rollers 24 are positioned between the feeding shaft 25 and the receiving shaft 26, with three support rollers 24 arranged in a V-shape between the two clamping ends of the clamping cylinder 22. One end of the strip 23 is connected to the feeding shaft 25, and the other end of the strip 23 passes around the multiple support rollers 24 and connects to the receiving shaft 26. The needle setting assembly 3 includes a fixing plate 31, which is disposed on the top of the mounting plate 21. A positioning groove 32 is formed on the surface of the fixing plate 31, and a correction plate 33 is provided on one side of the positioning groove 32. A mounting groove 311 is formed on the fixing plate 31, and a tool setting device 34 is embedded in the mounting groove 311.

[0019] Reference Figures 2-3As shown, in the above structure, both the feeding shaft 25 and the take-up shaft 26 are tumbledly connected to the mounting plate 21. The feeding shaft 25 is used to mount the rolled strip 23, while the take-up shaft 26 collects the wiped strip 23 into a roll. Multiple support rollers 24 are arranged between the feeding shaft 25 and the take-up shaft 26, providing support and guidance for the strip 23. Preferably, three of the support rollers 24 are arranged in a V-shape, forming a V-shaped structure with the V-shaped opening facing upwards. The two telescopic ends of the clamping cylinder 22 are located on both sides of the V-shaped opening. During actual operation, after the dispensing needle is inserted into the V-shaped opening, the clamping cylinder 22 actuates to make the strip 23 on both sides fit against the dispensing needle, wiping away any residual adhesive on the dispensing needle. As a preferred embodiment of this utility model, the tape 23 is a dust-free tape. After wiping the dispensing needle, the tape 23 is collected by the receiving shaft 26 to ensure that the tape 23 is used to wipe the dispensing needle after cleaning.

[0020] Reference Figure 5 As shown, the needle-setting assembly 3 and the adhesive-wiping assembly 2 in this utility model are designed as an integrated unit. Specifically, the fixing plate 31 in the adhesive-wiping assembly 2 is set on the top of the mounting plate 21. The positioning groove 32 on the fixing plate 31 serves as the positioning origin and works in conjunction with the calibration plate 33 to position the dispensing needle in the XY axis direction. The tool setter 34 is used to position the dispensing needle in the Z axis direction. Specifically, in actual operation, the replaced dispensing needle is applied to the calibration plate 33. The visual recognition camera identifies the relative position between the dispensing position and the origin to determine if the dispensing position is accurate. If not, the needle position is readjusted, and the dispensing adjustment steps are repeated. Next, the dispensing needle is brought into contact with the tool setter 34 to calibrate the Z-axis height of the dispensing needle. This ensures the accuracy of the subsequent dispensing position of the entire dispensing needle.

[0021] This invention uses a clamping cylinder 22 to clamp the material 23, thereby achieving the glue-wiping action of the dispensing needle and improving the efficiency of glue-wiping. Secondly, a calibration plate 33, a positioning groove 32, and a needle setter 34 are used to calibrate the installation position of the dispensing needle, ensuring the accuracy of the dispensing action. This invention integrates the glue-wiping mechanism and the needle-setting mechanism, resulting in a simple overall structure, minimal space occupation, and improved work efficiency.

[0022] Furthermore, referring to Figures 2-3 As shown, a limit nut 251 is provided at the end of the feeding shaft 25 near the material 23, and a drive source 261 is provided at the end of the receiving shaft 26 away from the material 23.

[0023] In this invention, the movement of the strip 23 is achieved by a drive source 261. Specifically, the rolled strip 23 is installed at one end of the unloading shaft 25. After passing over the support roller 24, the strip 23 is fixed on the take-up shaft 26. The drive source 261 drives the take-up shaft 26 to rotate and rewind the wiped strip 23. After a roll of strip 23 has been used, the limit nut 251 is removed and the strip 23 is replaced.

[0024] Furthermore, referring to Figure 4 As shown, a clamping platform 254 is provided circumferentially on the surface of the feeding shaft 25, and the clamping platform 254 is disposed between the strip 23 and the mounting plate 21; a locking nut 252 is provided at the end of the feeding shaft 25 away from the locking nut 252, and an elastic element 253 is provided between the locking nut 252 and the mounting plate 21.

[0025] Specifically, during installation, the feeding shaft 25 is inserted into the mounting plate 21, causing the clamping platform 254 to fit against the mounting plate 21. Then, the elastic element 253 and the locking nut 252 are installed at the end away from the clamping platform 254. The tension of the elastic element 253 presses the clamping platform 254 against the mounting plate 21, thus limiting the axial movement of the feeding shaft 25. As a preferred embodiment of this invention, a bearing is installed between the feeding shaft 25 and the mounting plate 21 to ensure smooth rotation of the feeding shaft 25.

[0026] Furthermore, a first sensor 27 is provided on the top of the mounting plate 21, and the detection end of the first sensor 27 is positioned directly opposite the strip 23.

[0027] Specifically, the first sensor 27 is positioned near the side of the feeding shaft 25 and directly facing the conveyor belt 23. Preferably, the first sensor 27 is a photoelectric sensor that detects the status of the conveyor belt 23 through photoelectric signals. When the conveyor belt 23 is used up, the first sensor 27 sends back a detection signal to remind the operator to replace the conveyor belt 23.

[0028] Furthermore, the mounting plate 21 is also provided with a detection shaft 29, which is located between the feeding shaft 25 and the support shaft. One end of the detection shaft 29 is fitted with a sensing wheel 291, and the two sides of the sensing wheel 291 are provided with second sensors 28.

[0029] Specifically, in actual operation, after each wiping, the drive source 261 drives the take-up shaft 26 to retract the wiped tape 23. While the tape 23 is moving, it drives the detection shaft 29 to rotate synchronously, which in turn drives the sensing wheel 291 to rotate. Preferably, the sensing wheel 291 has a multi-blade structure, and the second sensor 28 is a slotted photoelectric sensor, with the slotted photoelectric sensor located on both sides of the sensing wheel 291. In actual operation, the drive source 261 drives the tape 23 to move, the sensing wheel 291 rotates synchronously, and the second sensor 28 detects changes in the signal to determine whether the wiped tape 23 has been effectively retracted.

[0030] Furthermore, referring to Figure 6 As shown, the system also includes a housing 4, which comprises a first outer shell 41 and a second outer shell 42. The first outer shell 41 and the second outer shell 42 are fastened to both sides of the mounting plate 21, with the first outer shell 41 positioned closer to the material strip 23. Both the first outer shell 41 and the second outer shell 42 are detachably connected to the mounting plate 21. The surface of the first outer shell 41 has a first notch 412, which faces the clamping cylinder 22. The surface of the second outer shell 42 has a second notch 421, which faces the fixing plate 31.

[0031] Specifically, the first outer shell 41 fastens to the side of the mounting plate 21 where the material 23 is located, covering the material 23 to prevent external contamination. The first notch 412 is designed to facilitate the insertion of the dispensing needle without affecting normal dispensing operations. The two sides of the first outer shell 41 are connected to the mounting plate 21 by screw bolts, facilitating subsequent replacement of the material 23. The second outer shell 42 fastens to the other side of the mounting plate 21, protecting components such as the drive source 261 and the clamping cylinder 22. The second outer shell 424 is fixedly connected to the mounting plate 21 by bolts. Similarly, the second notch 421 facilitates needle alignment for the dispensing needle.

[0032] In one embodiment of the present invention, a waste glue box 5 is embedded in the top of the second outer shell 42.

[0033] Specifically, in actual operation, before applying glue, the glue inside the dispensing needle needs to be drained, and the drained glue is collected through the waste glue box 5.

[0034] In summary, this utility model introduces a glue-wiping and needle-aligning mechanism for a dispensing machine. This utility model uses a clamping cylinder 22 to hold the material 23, thereby achieving the glue-wiping action of the dispensing needle and improving the efficiency of glue-wiping. Secondly, the installation position of the dispensing needle is calibrated using a calibration plate 33, a positioning groove 32, and a needle-aligning device 34 to ensure the accuracy of the dispensing action. This utility model integrates the glue-wiping mechanism and the needle-aligning mechanism, resulting in a simple overall structure, small footprint, and improved work efficiency.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
