Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1-6The utility model provides a technical solution: a dispensing tool, including a dispensing machine 1; two connecting seats 2 are symmetrically fixedly installed on the dispensing machine 1, the same rotating seat 3 is rotatably installed on the two connecting seats 2, an annular plate 4 is fixedly installed on one side of the rotating seat 3, a material changing structure is installed on the annular plate 4, two fixed guide rods 5 are symmetrically fixedly installed on one side of the rotating seat 3, a horizontal adjustment structure is installed on the two fixed guide rods 5, and a linkage rod 6 is rotatably installed on the side of the two rotating seats 3 away from each other, and an angle adjustment structure is installed on the two linkage rods 6;

[0026] The material changing structure includes a connecting turntable 41, which is rotatably mounted on one side of the annular plate 4, a driven bevel gear 42 is fixedly mounted on one side of the connecting turntable 41, and the driven bevel gear 42 is rotatably mounted on the inner wall of the annular plate 4, a driving motor 43 is fixedly mounted on the bottom side of the annular plate 4, and an active bevel gear 44 is fixedly mounted on the output end of the driving motor 43, and the active bevel gear 44 is meshed with the driven bevel gear 42, a plurality of guide rods 45 are fixedly mounted on the connecting turntable 41, and the same support plate 46 is slidably mounted on two guide rods 45 on the same side, and the support plate 46 is movably mounted on one side of the annular plate 4, and a positioning tool 47 is fixedly mounted on the top side of the support plate 46;

[0027] The horizontal adjustment structure includes a fixed seat 51, which is fixedly mounted on one side of the two fixed guide rods 5, an adjusting motor 52 is fixedly mounted on the rotating seat 3, a screw rod 53 is fixedly mounted on the output end of the adjusting motor 52, one end of the screw rod 53 is rotatably mounted on the fixed seat 51, an adjusting plate 54 is threadedly mounted on the screw rod 53, and the adjusting plate 54 is slidably mounted on the two fixed guide rods 5, a linkage plate 55 is fixedly mounted on one side of the adjusting plate 54, and the linkage plate 55 is movably mounted on the bottom side of a corresponding support plate 46. The workpiece that needs to be glued is put into the positioning fixture 47, and the support plate 46 can be driven to make a circular motion by turning on the driving motor 43, so that the support plate 46 with the workpiece driven by the workpiece moves to the bottom of the glue dispensing head for glue dispensing. At this time, the driving motor 43 is turned off, and the support plate 4 6 will drive the corresponding arc strip 411 to slide in the annular groove 410 on the annular plate 4 while making circular motion, until the support plate 46 moves to the bottom of the dispensing head. During the process, the support plate 46 will drive the arc strip 411 to slide out of the annular groove 410, and make the arc strip 411 slide into the arc positioning groove 56 on the linkage plate 55. By turning on the adjustment motor 52, the corresponding support plate 46 can be driven to move, and then the horizontal position of the workpiece on the positioning tool 47 can be adjusted. After the dispensing is completed, the output end of the adjustment motor 52 is controlled to rotate in the reverse direction to make the support plate 46 slide and reset, so that the support plate 46 drives the arc strip 411 to correspond to the annular groove 410 on the annular plate 4 again, and then the drive motor 43 is turned on to make the support plate 46 do circular motion again to switch the workpiece.

[0028] In order to limit the moving direction of the support plate 46 and avoid deviation when the support plate 46 drives the workpiece to move, two limiting grooves 48 are provided on the inner wall of the support plate 46, and limiting sliders 49 are slidably installed in the two limiting grooves 48. The two limiting sliders 49 are respectively fixed on one end of the two guide rods 45. When the support plate 46 moves, it will slide on the two guide rods 45. At the same time, the support plate 46 will slide on the two limiting sliders 49 respectively through the two limiting grooves 48, thereby preventing the support plate 46 from slipping off the guide rod 45.

[0029] In order to limit the position of the annular plate 4, an annular groove 410 is provided on the inner wall of the annular plate 4, and an arc-shaped strip 411 is fixedly installed on one side of the support plate 46, and the arc-shaped strip 411 is adapted to the annular groove 410. An arc-shaped positioning groove 56 is provided on the inner wall of the linkage plate 55, and the arc-shaped strip 411 is adapted to the arc-shaped positioning groove 56. When the support plate 46 makes a circular motion, it will drive the corresponding arc-shaped strip 411 to slide in the annular groove 410 on the annular plate 4. The support plate 46 can avoid deviation under the influence of the arc-shaped strip 411 until the support plate 46 moves below the dispensing head. During the process, the support plate 46 will drive the arc-shaped strip 411 to slide out of the annular groove 410 and slide the arc-shaped strip 411 into the arc-shaped positioning groove 56 on the linkage plate 55. By turning on the adjustment motor 52, the corresponding support plate 46 can be driven to move.

[0030] In order to be able to adjust the horizontal position of the support plate 46 on which the workpiece to be glued is mounted, guide grooves 57 are provided on both sides of the adjustment plate 54, and the two fixed guide rods 5 are slidably installed in the two guide grooves 57 respectively. A threaded hole 58 is provided on the adjustment plate 54, and the screw rod 53 is threadedly installed in the threaded hole 58. The rotating screw rod 53 will drive the adjustment plate 54 to slide horizontally through the cooperation with the threaded hole 58. When the adjustment plate 54 slides, it will slide on the fixed guide rod 5 through the guide groove 57, thereby limiting the sliding direction of the adjustment plate 54, so that the linkage plate 55 drives the corresponding support plate 46 to move through the cooperation of the arc positioning groove 56 and the arc strip 411 of its inner wall.

[0031] The working principle is as follows: put the workpiece to be glued into the positioning fixture 47, and turn on the driving motor 43 to drive the active bevel gear 44 to rotate. The rotating active bevel gear 44 will drive the connecting turntable 41 to rotate by meshing with the driven bevel gear 42. The rotating connecting turntable 41 will drive the support plate 46 to make a circular motion through the cooperation with the guide rod 45, so that the support plate 46 with the workpiece drives the workpiece to move to the bottom of the glue dispensing head for glue dispensing. At this time, turn off the driving motor 43, and the support plate 46 will drive the corresponding arc strip 411 to slide in the annular groove 410 on the annular plate 4 while making a circular motion, until the support plate 46 moves to the bottom of the glue dispensing head. In the process, the support plate 46 will drive the arc strip 411 to slide in the annular groove 410 on the annular plate 4 until the support plate 46 moves to the bottom of the glue dispensing head. The arc strip 411 slides out of the annular groove 410, and makes the arc strip 411 slide into the arc positioning groove 56 on the linkage plate 55. By turning on the adjusting motor 52, its output end can drive the screw rod 53 to rotate on the fixing seat 51. The continuously rotating screw rod 53 will drive the adjusting plate 54 to slide horizontally through the cooperation with the threaded hole 58. The sliding adjusting plate 54 will drive the linkage plate 55 to slide, so that the linkage plate 55 drives the corresponding support plate 46 to move through the arc positioning groove 56 and the arc strip 411 on its inner wall. When the support plate 46 moves, it will slide on the two guide rods 45. At the same time, the support plate 46 will slide on the two limiting slide blocks 49 respectively through the two limiting slide grooves 48, so as to avoid the support plate 46 from sliding. The plate 46 slides off the guide rod 45, and then the horizontal position of the workpiece on the positioning tool 47 can be adjusted. After the dispensing is completed, the output end of the adjusting motor 52 is controlled to rotate in the opposite direction, so that the linkage plate 55 drives the support plate 46 to slide and reset, so that the support plate 46 drives the arc strip 411 to correspond to the annular groove 410 on the annular plate 4 again, and then the driving motor 43 is turned on to make the support plate 46 to make a circular motion again to switch the workpiece. During the process, the support plate 46 that completes the dispensing operation will drive the upper arc strip 411 to slide back into the annular groove 410, and at the same time, another adjacent support plate 46 will drive the arc strip 411 to slide into the arc positioning groove 56. At this time, if the adjusting motor 52 is turned on, the other can be adjusted. The horizontal position of a support plate 46 can drive the push block 63 to slide at its output end by opening two cylinders 64. The sliding push block 63 will drive the linkage shaft 62 to move in the linkage groove 65. During the process, the linkage shaft 62 will squeeze the linkage rod 6 and flip it by cooperating with the linkage groove 65. The flipped linkage rod 6 will drive the connecting shaft 61 to rotate on the connecting seat 2, so that the rotating connecting shaft 61 drives the rotating seat 3 to rotate, and the rotating seat 3 will drive the annular plate 4 to rotate when it rotates. The annular plate 4 will drive the angle of the support plate 46 to change through the guide rod 45, so that the angle of the support plate 46 and the workpiece in the positioning tooling 47 can be fine-tuned to dispense glue on the inclined holes on the workpiece.

[0032] Example 2: Figure 2-3In order to realize the dispensing operation of the inclined holes on the workpiece, an angle adjustment structure is arranged on the linkage rod 6, and the angle adjustment structure includes a connecting shaft 61, one end of the connecting shaft 61 is fixedly installed on one side of the linkage rod 6, and the other end of the connecting shaft 61 passes through the connecting seat 2 and is fixedly installed on one side of the rotating seat 3, and the connecting shaft 61 is rotatably installed on the connecting seat 2, and a linkage shaft 62 is movably installed on the linkage rod 6, and a push block 63 is fixedly installed on one side of the linkage shaft 62, and the push block 63 is slidably installed on the dispensing machine 1, and a cylinder 64 is fixedly installed on the dispensing machine 1, and the output end of the cylinder 64 is fixedly installed on one side of the push block 63, and a linkage groove 65 is opened on the inner wall of the linkage rod 6, and the linkage shaft 62 is movably installed on the linkage shaft In the movable groove 65, two cylinders 64 are turned on, so that their output ends can drive the push block 63 to slide, and the sliding push block 63 will drive the linkage shaft 62 to move in the linkage groove 65. During the process, the linkage shaft 62 will squeeze the linkage rod 6 and flip it by cooperating with the linkage groove 65. The flipped linkage rod 6 will drive the connecting shaft 61 to rotate on the connecting seat 2, so that the rotating connecting shaft 61 drives the rotating seat 3 to rotate, and the rotating seat 3 will drive the annular plate 4 to rotate when it rotates. The annular plate 4 will drive the angle of the support plate 46 to change through the guide rod 45, so that the angle of the support plate 46 and the workpiece in the positioning tooling 47 can be fine-tuned to dispense glue on the inclined holes on the workpiece. The remaining features are the same as those in Example 1.
