Description

Technical Field

[0001] This utility model belongs to the field of workpiece bonding technology, and in particular relates to a dispensing machine. Background Technology

[0002] A dispensing machine is a small, robotic, automated device widely used in semiconductor packaging, fixing and protecting electronic components on circuit boards, and applying adhesives and bonding small parts. When using a dispensing machine to dispense AB adhesive, the heat generated during mixing accelerates the curing process. To prevent the adhesive from hardening, the dispensing speed needs to be increased, leading to adhesive waste. Cooling can slow down the curing process and save adhesive. However, traditional air-cooling methods require frequent dispensing after mixing, resulting in significant waste. Furthermore, the dispensing machine only has a dispensing function; after dispensing, other equipment is needed to quickly place the parts to be bonded onto the applied adhesive, making the process complex. Summary of the Invention

[0003] The purpose of this invention is to provide a dispensing machine that has a good cooling effect on adhesive and can also be used for installing workpieces.

[0004] The purpose of this utility model is to solve the following problem:

[0005] A dispensing machine includes a base and a robotic arm that is fixedly mounted on the base and can rotate 360 ​​degrees and move up and down. The robotic arm has a mounting frame at its outer end on which a glue supply component, a water cooling component, a dispensing component, and a liftable vacuum suction cup component are mounted. The base has three or more workpiece clamping components. The glue supply component includes one or more glue supply chambers inside a cylinder, and each glue supply chamber has a power-driven glue pushing rod at its upper part.

[0006] As a further optimization of the above technical solution, the three or more workpiece clamping components include an L-shaped base plate fixed on the base, and three or more workpiece clamping components are fixed on the base plate.

[0007] As a further optimization of the above technical solution, the workpiece clamping assembly includes a rotary lifting cylinder driven by air pressure and controlled by a hydraulic reversing valve. The top of the piston rod extending from the upper end of the rotary lifting cylinder is fixedly connected to a horizontally arranged rotating arm. The outer end of the rotating arm is connected to a downwardly extending pressure rod, and the lower end of the pressure rod is connected to a pressure block.

[0008] As a further optimization of the above technical solution, the rotating arm is composed of two or more short arms connected together.

[0009] As a further optimization of the above technical solution, the vacuum suction cup assembly includes a vacuum suction cup and a workpiece cylinder for driving the vacuum suction cup to rise and fall, and a vacuum pump is connected to the spherical cavity at the bottom of the vacuum suction cup through a conduit.

[0010] As a further optimization of the above technical solution, a horizontal arm is connected to the lower end of the piston rod extending from the lower side of the workpiece cylinder. The vacuum suction cup is installed on the guide tube connector, which is installed at the outer end of the horizontal arm. The guide tube connector is connected to the vacuum pump through a guide tube.

[0014] The outstanding advantages of this utility model compared to the prior art are:

[0015] 1. This utility model uses a metal cooling chamber 27 and circulating water to cool the heat generated during the mixing of AB glue. In particular, the mixing tube is placed in the metal cooling chamber for direct cooling, which has a higher cooling efficiency than indirect cooling. In addition, the cavity wall and heat dissipation fins in the metal cooling chamber directly dissipate heat to the outside, resulting in good heat dissipation effect.

[0016] 2. This utility model is equipped with a vacuum suction cup assembly, which can use the degree set by the controller on a dispensing machine to vacuum adsorb and install the workpiece to be bonded, thus expanding the use function of the dispensing machine and improving work efficiency.

The inner cavity 23 of the pressure valve is provided with a valve core 22 driven by the piston rod 14 of the cylinder 17 to move up and down to close the glue outlet of the mixing tube 28 and squeeze out the glue, thus dispensing the glue to a set position. When the piston rod 14 of the cylinder 17 drives the valve core 22 to move upward, the glue outlet of the mixing tube 28 is opened, and the glue pusher 18 pushes the glue into the inner cavity 23 of the pressure valve for the next dispensing.
