It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0030] like Figures 1 to 6 As shown, a glue erasing device includes a support base 1, a glue erasing rack is slidably mounted on the support base 1, a glue erasing platform is provided on the glue erasing rack, and a glue erasing assembly is installed on the glue erasing rack; the glue erasing assembly includes a glue erasing tape 3, the glue erasing tape 3 is laid on the glue erasing platform, one end of the glue erasing tape 3 is connected to and wound around the unwinding device, and the other end of the glue erasing tape 3 is connected to and wound around the winding device, a tape unwinding adjustment device that cooperates with the glue erasing tape 3 is provided between the glue erasing platform and the unwinding device, and a tape winding adjustment device that cooperates with the glue erasing tape 3 is provided between the glue erasing platform and the winding device; the glue erasing rack is also equipped with a glue recovery device located below the glue erasing platform.

[0031] In order to obtain a better erasing effect, the erasing tape 3 is preferably a dust-free cloth tape.

[0032] The eraser frame includes a base 21 that is slidably connected to the support base 1, and a vertical frame is fixedly installed on the base 21. The vertical frame includes a side support frame 22 with a triangular structure and a rigid frame plate 23. The rigid frame plate 23 is made of steel plate, one side of the frame plate 23 is fixedly connected to the side support frame 22, and the bottom end of the frame plate 23 is fixedly connected to the base 21; the side support frame 22 adopts a triangular structure, which is more stable; the eraser platform and the eraser assembly are both installed on the frame plate 23 of the vertical frame.

[0033] Preferably, a slide cylinder 24 is installed between the base 21 and the support base 1 , the base 21 is fixedly connected to the power output slide of the slide cylinder 24 , and the cylinder body of the slide cylinder 24 also serves as a support body of the base 21 .

[0034] like Figure 2 As shown, the eraser platform includes a base 41, a platen 42, and an elastic assembly. The base 41 is fixedly mounted on the eraser frame, and the platen 42 is floatingly mounted on the base 41 via the elastic assembly. The upper surface of the platen 42 is always higher than the upper edge of the eraser frame to ensure that the eraser tape 3 on the platen 42 can erase the waste glue from the glue dispenser's piezoelectric valve spraying area. During the eraser process, the platen 42 floats under the action of the elastic assembly. If the platen 42 is lower than the eraser frame, the eraser frame will interfere with the eraser tape 3 during the eraser process, resulting in the area of ​​the glue dispenser to be erased not being able to contact the eraser tape 3. Preferably, the elastic assembly includes a guide rod 43 fixedly connected to the platen 42. The end of the guide rod 43 extends downward through the base 41 and is equipped with an adjustment nut. The guide rod 43 is sheathed with a floating spring 44 located between the platen 42 and the base 41.

[0035] The unwinding device includes a reel 51 mounted on the rubber eraser frame. The rubber eraser tape 3 is pre-wound on the reel 51. The reel 51 is connected to a reel shaft 52, which passes through the rubber eraser frame and is equipped with a tensioning mechanism.

A compression spring 55 and an adjusting nut are sequentially mounted on the reel shaft 52 outside the dynamic friction disc 54. The reel 51 is mounted on one side of the frame plate 23. The reel 51 and the rubber eraser platform are located on the same side of the frame plate 23. The fixed friction disc 53, dynamic friction disc 54, compression spring 55, and adjusting nut are located on the other side of the frame plate 23. The pressure of the compression spring 55 on the dynamic friction disc 54 can be adjusted by adjusting the nut, thereby adjusting the friction force between the dynamic friction disc 54 and the fixed friction disc 53, thereby adjusting the tension of the play reel 51.

[0036] The rewinding device includes a reel 61 mounted on the wiper frame, and the used wiper tape 3 is rewound on the reel 61. The reel 61 is connected to a stepper motor 62.

As a preferred method, a bearing can be installed between the limiting guide wheels 71 and the wheel axle to make the sliding smoother and the noise reduction effect good; a tensioning wheel 72 for adjusting the tension of the rubber tape 3 is installed on the rubber frame, and the tensioning wheel 72 and the limiting guide wheel 71 are located on both sides of the rubber tape 3, and the limiting guide wheel 71 is located below the rubber tape 3 for supporting the rubber tape 3, and the tensioning wheel 72 is located above the rubber tape 3 and pressed against the rubber tape 3 for adjusting the tension on the rubber tape 3. Specifically, a long hole 73 is installed on the eraser frame, and the axle of the tensioning wheel 72 passes through the long hole 73 and is installed with a locking nut. By adjusting the position of the tensioning wheel 72 in the long hole 73, the pressing force of the tensioning wheel 72 on the eraser tape 3 can be adjusted, thereby adjusting the tension of the eraser tape 3.

[0038] The tape rewinding and adjusting device includes a plurality of limiting guide wheels 71 mounted on the tape rubbing frame, which guide the tape 3 from the tape rubbing platform to the rewinding device. The limiting guide wheels 71 are mounted on the tape rubbing frame, and a tensioning wheel 72 is mounted on the tape rubbing frame to adjust the tension of the tape 3. The tensioning wheel 72 and the limiting guide wheels 71 are located on either side of the tape rubbing device. After exiting the unwinding device, the tape 3 passes through the limiting guide wheels 71 of the tape rewinding and adjusting device and enters the upper portion of the tape rubbing platform. After passing the upper portion of the tape rubbing platform, the limiting guide wheels 71 control the tape rubbing and adjusting device to change direction and extend toward the rewinding device. Similarly, the limiting guide wheels 71 of the tape rewinding and adjusting device are located above the tape rubbing platform, and the tensioning wheel 72 is located above the tape rubbing. The structure of the tensioning wheel 72 of the tape rewinding and adjusting device is the same as that of the tensioning wheel 72 of the tape rewinding and adjusting device, and will not be further described here.

[0039] The adhesive recovery device includes an adhesive recovery box 8 with an opening facing the adhesive tape 3. The adhesive recovery box 8 is located below the adhesive erasing platform and moves with the adhesive erasing frame. The adhesive recovery box 8 extends in the same direction as the extension of the adhesive tape 3 and can collect waste adhesive wiped off the adhesive erasing platform and waste adhesive that has not fallen off the adhesive tape 3 in time.

[0040] The length direction of the glue wiping device extends along the Y-axis, that is, the glue wiping frame slides along the Y-axis; the glue wiping device is relatively narrow in the X-axis direction and can enter between the two glue dispensing stations of the dual-channel glue dispensing machine. The extension direction of the support seat is the Z-direction, and the X-direction, Y-direction and Z-direction are perpendicular to each other. When the glue dispensing machine needs to be rubbed, the glue wiping device is assembled next to the station of the glue dispensing machine, the glue dispensing machine head is moved to the top of the glue wiping platform of the glue wiping device, the glue dispensing machine head is lowered along the Z-axis, the piezoelectric valve glue spraying part of the glue dispensing machine head contacts the glue tape 3, the slide cylinder 24 is actuated, driving the glue wiping frame to reciprocate along the X-axis, and the glue tape 3 wipes the glue spraying part of the piezoelectric valve back and forth; after the glue wiping is completed, the stepper motor 62 is actuated to drive the take-up reel 61 to rotate, pulling the glue tape 3 to be wound on the take-up reel 61.

[0041] This glue wiping device has a compact structure and a narrow structure design in the X-axis direction, which enables the glue wiping frame to be moved between the two dispensing stations of the dual-channel dispensing machine. During the glue wiping operation, no matter which dispensing station the glue dispensing machine head is in, the glue dispensing machine head only needs to move sideways a small distance to complete the glue wiping operation, shortening the moving stroke, which can not only ensure the glue wiping effect but also reduce the equipment beat.

[0042] A glue dispensing machine comprises the glue erasing device mentioned above.

[0043] The glue wiping device has a small width in the X direction, the sliding direction of the glue wiping frame is the Y direction, the extension direction of the support seat is the Z direction, and the X direction, Y direction and Z direction are perpendicular to each other; the dual-channel dispensing machine is provided with two dispensing stations, and the distance between the two dispensing stations is relatively small. The narrow design of the X axis enables the glue wiping frame and the components on the glue wiping frame to extend between the two dispensing stations, and is relatively close to the glue dispensing machine head, which facilitates the glue dispensing machine head located at any glue dispensing station to move over for glue wiping operations.

[0044] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
