Existing dispensing machines can achieve processes such as dotting, line drawing, circular or arc-shaped. The requirements for the dispensing process in modern industrial production are becoming increasingly strict. Traditional manual dispensing can no longer meet the industrial needs and is gradually replaced by automatic dispensing machines. Automatic dispensing machines are widely used in industrial manufacturing fields such as integrated circuits, printed circuit boards, electronic components, automotive parts, handbags, and packaging boxes, improving production efficiency and product quality.

[0003] However, currently, after the dispensing of the workpiece by the existing dispensing machine, the dispensed workpiece cannot be automatically removed from under the fixture and needs to be manually disassembled, thereby reducing production efficiency and unable to meet the usage requirements.

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0020] like Figures 1 to 3 The embodiment of the utility model shown preferably provides a UV glue automatic dispensing device, including a machine platform 1, on which a rotating platform 2, a stepping motor 3 and a dispensing component 4 are respectively arranged, the rotating platform 2 is connected to the driving shaft of the stepping motor 3, the dispensing component 4 is located above the rotating platform 2, and a plurality of fixtures 5 for positioning and placing workpieces are evenly arranged along the circumference of the rotating platform 2, and a plurality of discharge guide grooves 6 and a plurality of first arc-shaped perforations 7 are evenly arranged along the circumference of the rotating platform 2, and the plurality of fixtures 5 and the plurality of discharge guide grooves 6 are arranged in a staggered manner. A plurality of first arcuate through holes 7 are connected to a plurality of discharge guide grooves 6 in one-to-one correspondence, the center of the first arcuate through hole 7 is concentrically arranged with the center of the rotating platform 2, a second arcuate through hole 8 with an opening on one side is penetrated through the clamp 5, the second arcuate through hole 8 is connected to the first arcuate through hole 7 in one-to-one correspondence and the two are concentrically arranged, a lifting seat 9 and a cylinder 10 for driving the lifting seat 9 to move up and down are respectively arranged on the machine 1 below the rotating platform 2, and a push rod 11 that can pass through the first arcuate through hole 7 and the second arcuate through hole 8 in sequence is arranged at intervals on the lifting seat 9.

[0021] Specifically, through the cooperation of the stepping motor, the rotating platform and the dispensing component, the dispensing component dispenses glue to the workpieces in the fixture one by one, so as to speed up the production efficiency of batch dispensing of workpieces;

[0022] When the dispensing is completed, the movable seat is driven upward by the cylinder, so that the two push rods on the movable seat move upward accordingly, and pass through the first arc-shaped through-hole of the rotating platform and the second arc-shaped through-hole of the clamp in turn and abut against the lower side of the workpiece, thereby causing the workpiece to detach from the clamp and be supported by the two push rods to be located above the corresponding clamp. At this time, the stepper motor drives the rotating platform to rotate, and the first arc-shaped through-hole on the rotating platform moves relative to the push rod, so that the push rod is located above the unloading guide groove, and then reset by the cylinder, driving the movable seat and the push rod to move downward and reset to the bottom of the rotating platform, thereby causing the workpiece to fall into the unloading guide groove, and automatically transported by the downward inclination of the unloading guide groove, thereby realizing automatic unloading and output of the workpiece after the dispensing is completed, thereby improving production efficiency and meeting the needs of automated production.

[0023] The push rods are arranged at intervals on the lifting seat. There may be two or more push rods. The upper end surfaces of the push rods are flat. The combination of the plurality of push rods can meet the requirements of abutting and supporting the workpiece in a horizontal state.

[0024] Further, a connecting seat 12 is rotatably arranged on the machine table 1, the dispensing member 4 is arranged on the connecting seat 12, the lifting seat 9 is located directly below the dispensing member 4, and a transmission member 13 is connected between the lifting seat 9 and the connecting seat 12. The transmission member enables the connecting seat 12 to swing up and down relative to the machine table 1 synchronously as the lifting seat 9 moves up and down. Specifically, by arranging the transmission member and the connecting seat, interference between the dispensing member and the workpiece lifted by the ejector rod can be effectively avoided. That is, when the workpiece placed in the fixture is lifted upward by the ejector rod, the transmission member can drive the connecting seat to move upward and flip, and when the ejector rod resets downward, the connecting seat flips downward and resets synchronously.

[0025] Further, the transmission member 13 includes a connecting rod 14, and a fixed shaft 15 extends from one side of the connecting seat 12. The connecting rod 14 is hinged between the fixed shaft 15 and the lifting seat 9. Specifically, when the lifting seat is driven by the air cylinder to move upward, the transmission drives the connecting seat to flip upward relative to the machine table. Conversely, when the lifting seat moves downward and resets, the transmission drives the connecting seat to flip downward and reset relative to the machine table.

[0026] Further, a downwardly inclined discharge plate 16 is arranged on one side of the machine table 1, and a plurality of discharge guide grooves 6 rotate with the rotary platform 2 and are respectively butted with the discharge plate 16 one by one. Then, the workpiece located in the discharge guide groove is output to the outside of the machine table through the discharge plate.

[0027] Further, the lower end of the discharge plate 16 protrudes outward from one side of the machine table 1. Then, it is convenient to be butted and conveyed with an external conveyor belt, and the workpiece can be directly output through the discharge plate and fall onto the external conveyor belt.

[0028] Further, the fixture 5 includes a bottom plate 51, and two positioning blocks 52 and a positioning column 54 respectively arranged on the bottom plate 51. The two positioning blocks 52 are arranged at intervals and distributed on both sides of the workpiece, and the second arc-shaped through hole 8 is formed on the bottom plate 51. Specifically, through the cooperation between the positioning column and the positioning hole inside the workpiece, and the two positioning blocks are limited and distributed to abut against both sides of the workpiece, so as to realize the positioning placement of the workpiece.

[0029] Further, vertical shafts 53 are arranged on the machine table 1 at intervals, and the lifting seat 9 is movably sleeved on the vertical shafts 53 through linear bearings. Then, the up and down movement of the lifting seat relative to the machine table is realized.

[0030] Further, a soft pad is arranged on the inner wall of the discharge guide groove 6. Thus, the problem of workpiece wear caused by friction between the workpiece and the discharge guide groove can be effectively avoided.

[0031] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
