Description

Technical Field

[0001] The present invention relates to the field of automatic glue dispensing machines, and more specifically, to an automatic glue dispensing machine and a control method thereof. Background Art

[0002] When it is necessary to dispense glue on the material, the material will be placed on the support seat first, and then the dispensing needle will move forward and backward, left and right, and vertically as needed to perform dispensing connection on the reserved position of the material.

[0003] At present, in order to facilitate the dispensing of materials, a base will be produced during mass production. When placing the materials, you only need to place the materials on the base. Through the positioning of the base, the dispensing needle only needs to run to the specified position each time to perform dispensing.

[0004] However, the base needs to be manufactured by a mold to match the fixed shape of the material. When the shape or size of the material changes, or when the production batch is small and the base mold is not made, it is difficult to accurately control the dispensing position.

[0005] Therefore, it is necessary to propose an automatic dispensing machine and a control method thereof to solve the above problems. Summary of the invention

[0006] In order to overcome at least one defect (shortcoming) of the above-mentioned prior art, the present invention provides an automatic glue dispensing machine and a control method thereof.

[0007] In order to solve the above technical problems, the technical solution of the present invention is as follows: an automatic glue dispensing machine, comprising a glue dispensing machine body, a support frame, a lateral moving mechanism, a longitudinal moving mechanism, a vertical moving mechanism, a glue dispensing needle and a control unit arranged on the glue dispensing machine body, wherein the longitudinal moving mechanism is arranged on the glue dispensing machine body, the support frame is arranged on both sides of the glue dispensing machine body, the lateral moving mechanism is arranged on the support frame, the vertical moving mechanism is arranged on the lateral moving mechanism, and the glue dispensing needle is arranged on the vertical moving mechanism:

[0008] The longitudinal moving mechanism is provided with a supporting seat for supporting materials, and a concentric centering ring point is provided in the middle of the supporting seat;

[0009] A transverse positioning device and a longitudinal positioning device are respectively provided on the edges of the supporting seat, and a calibration detection probe is provided on the vertical moving mechanism for performing positioning detection on the centering ring point, the transverse positioning device and the longitudinal positioning device. The calibration detection probe fine-tunes the angle of the offset of the transverse moving mechanism and the longitudinal moving mechanism according to the detection of the centering ring point, the transverse positioning device and the longitudinal positioning device. Through the setting of the transverse moving mechanism, the longitudinal moving mechanism and the vertical moving mechanism, the material and the dispensing needle can be moved to facilitate dispensing. Compared with the prior art, the present invention provides a concentric centering ring point in the middle of the supporting seat. When the material is set on the centering ring point, the calibration detection probe will detect the centering ring point, the transverse positioning device and the longitudinal positioning device to determine the center position offset of the material, thereby fine-tuning the transverse moving mechanism and the longitudinal moving mechanism to facilitate more accurate dispensing.

[0063] Embodiment 1

[0064] In the present embodiment, a fixed centering ring point is provided on the supporting seat. Since the centering ring point includes a first centering ring body, a second centering ring body and a third centering ring body which are concentrically arranged in sequence, when the material is placed on the supporting seat without a base mold, it is only necessary to align the through hole reserved for the material with the centering ring point. Since the material is placed, even if it is aligned with the centering ring point, there will still be deviations. After the material is placed, the detection probe of the present invention will respectively detect the centering sensors on the first centering ring body, the second centering ring body and the third centering ring body. When the material is placed with deviations, the center of the reserved through hole in the material will deviate from the first centering ring body, which is not easy to detect. However, the amount of deviation can be quickly judged by the shielding area of ​​the outermost third centering ring body through the through hole. Therefore, when dispensing, the dispensing can be made more accurate by adjusting the movement of the lateral moving mechanism and the longitudinal moving mechanism.

When the positioning through hole is large, the centering ring can be set to a movable structure. When the rotation control motor drives the driving gear to rotate, the through groove on the driving gear will drive the movable connecting rod to rotate through the pushing bar, so that the third centering ring body is pushed open, thereby increasing the detection area.
