[0001] This application belongs to the technical field of automatic dispensing machines, and specifically relates to a rotary automatic dispensing machine. Background Art

[0002] A dispensing machine, also known as a glue coating machine, a drop glue machine, a glue injection machine, a potting machine, etc., is specialized for controlling fluids. It is an automated machine that can drip and coat fluids on the surface or inside of products, and can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, no wire drawing, no glue leakage, and no dripping. The dispensing machine is mainly used to accurately dot, inject, coat, and drip glue, paint, and other liquids in the product process to each precise position of the product, and can be used to achieve dotting, line drawing, circular or arc-shaped dispensing.

[0003] For example, a rotary automatic dispensing machine disclosed in the patent with the publication number CN207056905U includes a fixed frame, a protective plate, a dispensing groove, and a fixed groove. An adjustment shaft is installed inside the fixed frame, and the bottom end of the adjustment shaft is connected to a conveying device. A dispensing plate is fixed to the top end of the conveying device, and a buffer column is installed at the bottom end of the conveying device. The protective plates are inlaid at both ends of the conveying device. A rotating shaft is installed at the top end of the adjustment shaft, and the rotating shaft is connected to a dispensing frame. A moving guide rail is inlaid at the bottom end of the dispensing frame, and a dispensing chamber is arranged inside the moving guide rail. A dispensing head is installed at the bottom end of the dispensing chamber. The dispensing groove is opened on the surface of the dispensing plate, and sliding card slots are installed at both ends of the dispensing groove. The inside of the sliding card slot is connected to a limiting rod. This rotary automatic dispensing machine has a simple and novel structure. When in use, the buffer column at the bottom end of the conveying device can disperse the pressure generated during dispensing to ensure the stable operation of the conveying device.

[0004] However, when the automatic dispensing machine of this application draws a circular dispensing arc with a relatively large radius, the non-eccentric single dispenser moves at a relatively slow speed during dispensing, thereby affecting the processing efficiency. Summary of the Utility Model

[0005] The purpose of this application is to provide a rotary automatic dispensing machine to solve the problem that when the above-mentioned rotary automatic dispensing machine draws a circular dispensing arc with a relatively large radius, the non-eccentric single dispenser moves at a relatively slow speed during dispensing, thereby affecting the processing efficiency.

[0006] The technical solution adopted in this application is as follows: A rotary automatic dispensing machine includes a dispensing table. The bottom of the dispensing table is fixedly connected to a rotating shaft. The bottom of the rotating shaft is rotatably connected to an adjusting plate. A scale plate is fixedly installed on the side end of the adjusting plate. Two sliders are slidably connected to both sides of the bottom of the adjusting plate. The bottom left end of the adjusting plate is slidably connected to a first fixing block through a slider. The bottom right side of the adjusting plate is slidably connected to a second fixing block through a slider. The side end of the first fixing block is fixedly connected to an angle plate. An installation groove is opened inside the angle plate. An adjusting bolt is threadedly connected inside the installation groove. Installation plates are threadedly connected to both ends of the surface of the installation groove through the adjusting bolt. A dispensing tube is fixedly installed on the side end of the installation plate. A laser locator is fixedly installed at the bottom of the adjusting plate and on one side of the middle.

[0007] By adopting the above technical solution, the bottom of the dispensing table is used to install the dispensing device. Rotating the rotating shaft can drive the adjusting plate at the bottom of the rotating shaft to rotate. The rotating shaft is located at the center position of the adjusting plate. The laser locator at the bottom of the rotating shaft is located directly below the rotating shaft. The laser locator can position the center position of the processing point. The scale plate installed on the side end of the adjusting plate can be used to measure the radius of the circular arc that needs to be dispensed. Two slidable sliders are installed at both ends of the adjusting plate. The positions of the first fixing block and the second fixing block at the bottom can be adjusted through the scale plate and the sliders. The same dispensing devices are installed on the side ends of the first fixing block and the second fixing block. By adjusting the position of the dispensing device from the axis center, the dispensing device can be changed into an eccentric double-headed dispensing machine of different sizes. The angle plate can be used to adjust the inclination angle of the dispensing device. When dispensing at a position with a curvature such as the side end of the material, the angle of the dispensing tube can be adjusted through the installation plate and the adjusting bolt on the surface of the angle plate. Rotating the adjusting bolt can release the limiting effect of the adjusting bolt on the installation plate and the installation groove, allowing the installation plate to slide on the side end of the angle plate, thereby driving the dispensing tube to rotate on the side end of the angle plate. For a traditional non-eccentric single-headed dispensing machine, when dispensing a circular arc with a large dispensing radius, it can only use the moving devices on the X and Y axes for dispensing, with slow efficiency and accuracy. This device can use the laser locator to position the center point of the circular arc. By moving the slider, the distance between the two dispensing devices and the axis center can be adjusted to make the distance of the dispensing device the same as the radius of the circular arc. Then, rotating the rotating shaft can quickly complete the dispensing of the circular arc. It can quickly and accurately dispense circular arcs of different sizes, improving the processing efficiency.

[0008] In a preferred embodiment, the bottom end of the dispensing tube is fixedly connected to a dispensing head. The top of the dispensing tube is fixedly connected to an air inlet tube. A piston is slidably connected inside the dispensing tube.

[0009] By adopting the above technical solution, the intake pipe is used to connect the gas delivery pipe. Gas enters the interior of the dispensing tube from the intake pipe, which can push the piston downward, and then push the material glue between the dispensing tube and the piston to be discharged from the dispensing head, completing the dispensing.

[0010] In a preferred embodiment, a second electric slide rail is installed at the side end of the dispensing table, and a horizontal bracket is fixedly connected to the bottom of the second electric slide rail.

[0011] By adopting the above technical solution, the horizontal bracket is used to install the second electric slide rail. Starting the second electric slide rail can drive the dispensing table on the surface of the second electric slide rail to move left and right. When dispensing a linear pattern, the second electric slide rail can quickly move the dispensing table left and right, and then move the dispensing device left and right.

[0012] In a preferred embodiment, a vertical bracket is fixedly connected to the side end of the horizontal bracket, a first electric slide rail is installed at the inner side end of the vertical bracket, and a workbench is fixedly installed at the side end of the first electric slide rail.

[0013] By adopting the above technical solution, the workbench is used to install the dispensing machine moving device. Starting the first electric slide rail can drive the vertical bracket to move back and forth, and then drive the dispensing device to move back and forth.

[0014] In a preferred embodiment, a compressed air machine is fixedly installed at the outer side end of the vertical bracket, and an air delivery pipe is fixedly connected to the top of the compressed air machine.

[0015] By adopting the above technical solution, the workbench is used to install the dispensing machine moving device. Starting the first electric slide rail can drive the vertical bracket to move back and forth, and then drive the dispensing device to move back and forth.

[0016] In a preferred embodiment, an operating table is fixedly installed at the front end of the workbench, and a sliding groove is formed on the surface of the workbench.

[0017] By adopting the above technical solution, the operating table can facilitate the operator to operate the equipment, and the interior of the sliding groove is used to install the moving device of the material placing plate.

[0018] In a preferred embodiment, a motor is fixedly installed inside the sliding groove, a screw rod is fixedly connected to the side end of the motor, the other end of the screw rod away from the motor is rotatably connected to the sliding groove, and an installation table is threadedly connected to the surface of the screw rod.

[0019] By adopting the above technical solution, starting the motor can drive the screw rod to rotate, and then drive the installation table to move back and forth inside the sliding groove. The position of the object to be processed can be quickly adjusted.

[0020] In a preferred embodiment, a hydraulic rod is fixedly installed on the top of the installation table, and a material placing plate is fixedly installed on the top of the hydraulic rod.

[0021] By adopting the above technical solution, starting the hydraulic rod can drive the material placing plate to move up and down, and the surface of the material placing plate is used to place the objects to be dispensed.

[0022] To sum up, due to adopting the above technical solution, the beneficial effects of this application are:

[0023] In this application, the bottom of the dispensing table is used to install the dispensing device. Rotating the rotating shaft can drive the adjusting plate at the bottom of the rotating shaft to rotate. The rotating shaft is located at the center of the adjusting plate, and the laser locator at the bottom of the rotating shaft is located directly below the rotating shaft.

The bottom of the dispensing table 10 is fixedly connected to a rotating shaft 11. The bottom of the rotating shaft 11 is rotatably connected to an adjusting plate 18. A scale plate 20 is fixedly installed on the side end of the adjusting plate 18. Two sliders 19 are slidably connected to both sides of the bottom of the adjusting plate 18. The left bottom end of the adjusting plate 18 is slidably connected to a first fixing block 22 through the slider 19. The right bottom end of the adjusting plate 18 is slidably connected to a second fixing block 23 through the slider 19. The side end of the first fixing block 22 is fixedly connected to an angle plate 24. An installation groove 25 is opened inside the angle plate 24. An adjusting bolt 27 is threadedly connected inside the installation groove 25. Both ends of the surface of the installation groove 25 are threadedly connected to a mounting plate 26 through the adjusting bolt 27. A dispensing tube 28 is fixedly installed on the side end of the mounting plate 26. A laser locator 21 is fixedly installed at the bottom of the adjusting plate 18 and on one side of the middle. The bottom of the dispensing table 10 is used to install the dispensing device. Rotating the rotating shaft 11 can drive the adjusting plate 18 at the bottom of the rotating shaft 11 to rotate. The rotating shaft 11 is located at the center position of the adjusting plate 18. The laser locator 21 at the bottom of the rotating shaft 11 is located directly below the rotating shaft 11. The laser locator 21 can position the center position of the processing point.

[0032] The scale plate 20 installed at the side end of the adjusting plate 18 can be used to measure the radius of the circular arc that needs to be dispensed. Two slidable sliders 19 are installed at both ends of the adjusting plate 18. The positions of the first fixed block 22 and the second fixed block 23 at the bottom can be adjusted through the scale plate 20 and the sliders 19. The dispensing devices with the same structure are installed at the side ends of the first fixed block 22 and the second fixed block 23. By adjusting the position of the dispensing device from the axis center, the dispensing device can be changed into an eccentric double-headed dispensing machine with different sizes. The angle plate 24 can be used to adjust the inclination angle of the dispensing device. When dispensing at a position with a curvature such as the side end of the material, the angle of the dispensing tube 28 can be adjusted through the mounting plate 26 and the adjusting bolt 27 on the surface of the angle plate 24. Rotating the adjusting bolt 27 can release the limiting effect of the adjusting bolt 27 on the mounting plate 26 and the mounting groove 25;

[0033] Let the mounting plate 26 slide at the side end of the angle plate 24, thereby driving the dispensing tube 28 to rotate at the side end of the angle plate 24. For a traditional non-eccentric single-headed dispensing machine, when dispensing a circular arc with a large dispensing radius, only the moving devices of the X and Y axes can be used for dispensing, and the efficiency and accuracy are slow. This device can use the laser locator 21 to locate the center point of the circular arc. By moving the slider 19, the distance between the two dispensing devices and the axis center can be adjusted to make the distance of the dispensing device the same as the radius of the circular arc. Then, rotating the rotating shaft 11 can quickly complete the dispensing of the circular arc. Facing circular arcs of different sizes, it can quickly and accurately dispense, improving the processing efficiency.

The cross bracket 8 is used to install the second electric slide rail 9. Starting the second electric slide rail 9 can drive the dispensing table 10 on the surface of the second electric slide rail 9 to move left and right. When dispensing a linear pattern, the second electric slide rail 9 can be used to quickly move the dispensing table 10 left and right, thereby moving the dispensing device left and right.

[0036] Refer to Figure 1, a longitudinal bracket 5 is fixedly connected to the side end of the transverse bracket 8, a first electric slide rail 4 is installed at the inner side end of the longitudinal bracket 5, and a workbench 1 is fixedly installed at the side end of the first electric slide rail 4. The workbench 1 is used for installing the dispensing machine moving device. Starting the first electric slide rail 4 can drive the longitudinal bracket 5 to move back and forth, and further drive the dispensing device to move back and forth.

[0037] Refer to Figure 1 , a compressed air machine 6 is fixedly installed at the outer side end of the longitudinal bracket 5, and an air delivery pipe 7 is fixedly connected to the top end of the compressed air machine 6. The inside of the compressed air machine 6 is used for storing gas, and the gas can be connected to the air delivery pipe through the air delivery pipe 7 and enter the inside of the dispensing pipe 28 from the air delivery pipe.

[0038] Refer to Figure 1 , an operating platform 2 is fixedly installed at the front end of the workbench 1, and a chute 3 is provided on the surface of the workbench 1.

[0039] Refer to Figure 2 , a motor 13 is fixedly installed inside the chute 3, a screw rod 14 is fixedly connected to the side end of the motor 13, the other end of the screw rod 14 away from the motor 13 is rotatably connected to the chute 3, and an installation table 15 is threadedly connected to the surface of the screw rod 14. Starting the motor 13 can drive the screw rod 14 to rotate, and further drive the installation table 15 to move back and forth inside the chute 3. The position of the object to be processed can be quickly adjusted.

[0040] Refer to Figure 2 , a hydraulic rod 16 is fixedly installed at the top of the installation table 15, and a material placing plate 17 is fixedly installed at the top of the hydraulic rod 16. Starting the hydraulic rod 16 can drive the material placing plate 17 to move up and down, and the surface of the material placing plate 17 is used for placing the object to be dispensed.

[0041] The implementation principle of an embodiment of the rotating type automatic dispensing machine of the present application is as follows: the bottom of the dispensing table 10 is used for installing the dispensing device. Rotating the rotating shaft 11 can drive the adjusting plate 18 at the bottom of the rotating shaft 11 to rotate. The rotating shaft 11 is located at the axis position of the adjusting plate 18, and the laser locator 21 at the bottom of the rotating shaft 11 is located directly below the rotating shaft 11. The laser locator 21 can locate the axis position of the processing point.

Two slidable sliders 19 are installed at both ends of the adjusting plate 18. The positions of the first fixing block 22 and the second fixing block 23 at the bottom can be adjusted through the scale plate 20 and the sliders 19. The same dispensing devices are installed at the side ends of the first fixing block 22 and the second fixing block 23. By adjusting the position of the dispensing device from the axis, the dispensing device can be changed into an eccentric type double-head dispensing machine of different sizes. The angle plate 24 can be used to adjust the inclination angle of the dispensing device.

[0042] When dispensing glue at a position with an arc, such as the side end of a material, the angle of the glue dispensing tube 28 can be adjusted through the mounting plate 26 and the adjusting bolt 27 on the surface of the angle plate 24. Rotating the adjusting bolt 27 can contact the adjusting bolt 27 to limit the mounting plate 26 and the mounting groove 25, allowing the mounting plate 26 to slide on the side end of the angle plate 24, thereby driving the glue dispensing tube 28 to rotate on the side end of the angle plate 24. For a traditional non-eccentric single-head glue dispenser, when dispensing glue on a circular arc with a large dispensing radius, it can only use the moving devices of the X and Y axes for glue dispensing, with slow efficiency and accuracy. This device can use the laser locator 21 to locate the center point of the circular arc, adjust the distance between the two glue dispensing devices and the axis by moving the slider 19, make the distance of the glue dispensing device the same as the radius of the circular arc, and then quickly complete the glue dispensing of the circular arc by rotating the rotating shaft 11. It can quickly and accurately dispense glue for circular arcs of different sizes, improving the processing efficiency.
