DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] See the appendix Figures 1 to 5As shown in the figure, this embodiment provides an automatic dispensing machine, which includes a machine table 1, and a feeding device 2, a dispensing device 3, and a workpiece clamping device 4 arranged on the machine table. The feeding device 2 includes a coupling fixture tooling 24 on which a plurality of workpieces are fixedly arranged at equal intervals, a slide rail 21 for supporting the coupling fixture tooling 24, a clamping mechanism 23 for clamping the coupling fixture tooling 24, and a conveying mechanism 22 for driving the coupling fixture tooling 24 to move on the slide rail 21. The clamping mechanism 23 is arranged on the conveying mechanism 22. The slide rails are a pair of parallel slide rails. The coupling fixture tooling 24 is installed on the slide rail 21. A clamping groove 241 adapted to the clamping mechanism 23 is arranged on the coupling fixture tooling 24. The conveying mechanism 22 includes a conveying motor 221, a lead screw 224, a slider 222, and a guide rail 223. The guide rail 223 is fixedly arranged on the machine table 1. The slider 222 is connected to the guide rail 223 and moves along the guide rail 223. One end of the lead screw 224 is in transmission connection with the conveying motor 221, and the other end passes through the slider 222. The clamping mechanism 23 is arranged on the slider 222. The lead screw 224 serves as a transmission component to convert rotational motion into linear motion. A nut makes the slider 222 move linearly on the guide rail 223 through the spiral groove of the lead screw 224. The guide rail 223 is a platform for supporting the slider 222, ensuring the movement track and stability of the slider 222, enabling very high position accuracy and repeatability accuracy, and having a longer service life. The clamping mechanism 23 includes a chuck 233, a lifting cylinder 231 for driving the chuck 233 to lift, and a clamping cylinder 232 for opening or closing the chuck 233. The conveying mechanism 22 operates to drive the clamping mechanism 23, and the clamping mechanism 23 clamps the coupling fixture tooling 24 to complete the feeding and discharging actions. The dispensing device 3 is arranged above the slide rail 21 and includes a glue discharging mechanism 31, a fixing mechanism 32, and a rotating mechanism 33. The glue discharging mechanism 31 is a glue cylinder, and the glue cylinder is connected with an air duct for controlling the glue discharging amount. The rotating mechanism 33 is a gear belt conveying mechanism, including a rotating motor 331, a driving wheel 332, a driven wheel 333, and a belt 334. The rotating motor 331 is rotationally connected to the driving wheel 332. The belt 334 is sleeved on the driving wheel 332 and the driven wheel 333. A fixing mechanism is arranged on the driving wheel 332. The fixing mechanism includes a plurality of fastening structures for fixing the glue discharging mechanism 31 so that the glue discharging head remains coaxial with the driven wheel 333. The clamping device 4 includes a workpiece chuck 43, a workpiece lifting cylinder 41 for driving the workpiece chuck 43 to lift, and a workpiece clamping cylinder 42 for opening or closing the workpiece chuck 43.

[0024] When the dispensing machine is operating, the drive motor 221 of the conveyor mechanism 22 drives the lead screw 224. As a transmission component, the lead screw 224 converts rotational motion into linear motion. The nut causes the slider 222 to move linearly on the guide rail 223 through the helical groove of the lead screw 224. Through the control system, the slider 222 is moved to the position below the coupling fixture tooling to be grasped. The lifting cylinder 231 of the clamping mechanism 23 is activated, and the conveying chuck 233 reaches the designated position. Subsequently, the telescopic cylinder drives the chuck 233 to clamp the clamping slot 241 of the coupling fixture tooling 24. Then, the drive motor 221 drives the lead screw 224, causing the slider 222 to drive the coupling fixture tooling 24 to the designated processing position through the tooling clamping mechanism 23. When the workpiece to be processed reaches the processing position, the workpiece lifting cylinder 41 of the clamping device 4 drives the workpiece chuck 43 to the designated position. The workpiece clamping cylinder 42 is activated to drive the workpiece chuck 43 to clamp the workpiece to be processed. Subsequently, the rotation motor 331 is activated to drive the glue dispensing mechanism 31 to rotate, and the glue dispensing mechanism 31 dispenses glue to complete the dispensing. After the dispensing action is completed, the workpiece clamping cylinder 42 of the clamping device 4 is activated to release the workpiece. The workpiece lifting cylinder 41 is activated to lower the workpiece chuck 43. Then, the drive motor 221 is activated to convey the next workpiece to be processed to the processing position.

[0025] In a preferred embodiment: The coupling fixture is a general fixture in the coupling welding process. A brightener is connected to each workpiece to be processed on the fixture, so that it is possible to avoid frequent disassembly of the workpiece to be processed during the processing, improving the processing efficiency and the product qualification rate.
